I need to iterate through every element in an n-dimensional matrix in MATLAB. *L_C); L_series=50*(1/(3*10^(8)))*sqrt(epsilon_re). Your question is kind of unclear but what about just: This assumes that the length of completerange divides perfectly by rangewindow, if it doesn't then it's easy enough to just pad with NaNs. otherwise that's what i would have used too. Connect and share knowledge within a single location that is structured and easy to search. epsilon_re=0.5*(epsilon_r+1)+0.5*(epsilon_r-1)*(1+12*(H./W_C)).^(-0.5); C_I=0.5*epsilon_o*(epsilon_r+1)*(5.5. If you look deeper into the other uses of size you can see that you can actually get a vector of the size of each dimension. MathWorks is the leading developer of mathematical computing software for engineers and scientists. You could make G a logical array by calling, array before assigning values into its elements. Based on your location, we recommend that you select: . As everyone else is stating, if all he wants is each cell, liner indexing is best. Choose a web site to get translated content where available and see local events and One caveat on outputs if my_func returns outputs of different sizes and types when it operates on different elements of A, then outArgs will have to be made into a cell array. Why did the Soviets not shoot down US spy satellites during the Cold War? If not what is the shortest and cleanest way of accomplishing this?

Use a normal for loop instead of a foreach, so that you get an explicit loop counter: If you want to use string based indexed arrays, and know that the string indexes are equal between arrays, you can stick with the foreach construct, Not the most efficient, but a demonstration of SPL's multipleIterator. for instant: So, I should have 16 results. Based on your location, we recommend that you select: . *L_C); L_series=50*(1/(3*10^(8)))*sqrt(epsilon_re). 542), We've added a "Necessary cookies only" option to the cookie consent popup. yes but do you want this as a 2D matrix? At each dimmension we have as many digits as the lenght of the dimmension. (so t1 doesn't exist). The result is, we can access each element in turn of a general n-d array using a single loop. For example, lets apply a defined function to each element of a cell. epsilon_re=0.5*(epsilon_r+1)+0.5*(epsilon_r-1)*(1+12*(H./W_C)).^(-0.5); C_I=0.5*epsilon_o*(epsilon_r+1)*(5.5. Iterating through n-dimmensional array can be seen as increasing the n-digit number. W = 0.50, L = 6.00, C_I = 0.000000, L_series = 0.000002, R_series = 0.203961 R. Ruby.

How can I remove a specific item from an array in JavaScript? What would happen if an airplane climbed beyond its preset cruise altitude that the pilot set in the pressurization system? Note the sequence by which the elements are displayed on the command window, and this is the sequence of the linear indexing. W = 0.80, L = 6.00, C_I = 0.000000, L_series = 0.000002, R_series = 0.127475 You first create a function handle to this function: If A is a matrix (of type double, single, etc.) ;) I just ran that code too, @rayryeng i'm understanding! Unable to complete the action because of changes made to the page. I was only looking for a response that returns the value at the 10, 100 and 1000th place mark on the series. MATLAB uses a 32 bit integer to store these indexes. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. @TalDarom - I did. As pointed out in a few other answers, you can iterate over all elements in a matrix A (of any dimension) using a linear index from 1 to numel(A) in a single for loop. Based on your location, we recommend that you select: . Good luck! Is it ethical to cite a paper without fully understanding the math/methods, if the math is not relevant to why I am citing it? We want to know which one is going to hit the table first and which one. Find centralized, trusted content and collaborate around the technologies you use most. You could make a recursive function do the work. m_array = zeros (value 1, value 2) Explanation: This is the first way to declare the 2D array in Matlab, here we use the zeros () function and inside the zeros () function we need to pass the value 1 and value 2 as shown in the above statement. A nested loop would look like this: Theme Copy [row,col] = size (B); for N = 1:col for M = 1:row A = (B (M,N)*Z)/B (1,2); disp (A) end end The first loop will start at column 1, then the second loop goes through all rows. https://www.mathworks.com/matlabcentral/answers/279474-iterating-over-an-array-using-a-for-loop, https://www.mathworks.com/matlabcentral/answers/279474-iterating-over-an-array-using-a-for-loop#comment_2601190, https://www.mathworks.com/matlabcentral/answers/279474-iterating-over-an-array-using-a-for-loop#comment_2600315, https://www.mathworks.com/matlabcentral/answers/279474-iterating-over-an-array-using-a-for-loop#answer_218291, https://www.mathworks.com/matlabcentral/answers/279474-iterating-over-an-array-using-a-for-loop#answer_1164715.

In a matrix, there are two kinds of indexing; one is the row and column indexing in which we have to give the row and column number to access an element present in the matrix, second is the linear indexing in which we can access an element using only its linear index. Python. W = 0.65, L = 7.50, C_I = 0.000000, L_series = 0.000002, R_series = 0.196116 Summing elements of one Matrix according to the the values in another matrix into an array. Scheme.

If there are any outputs from my_func, these are placed in outArgs, which will be the same size/dimension as A. Edit: If you want the steps to be of RangeWindow and not 1, replace for m = 1 : length (CompleteRange) - RangeWindow with: for m = 1 : RangeWindow : length (CompleteRange) - RangeWindow Share Improve this answer Follow edited Feb 26, 2015 at 10:10 Objective-C. Pascal. After getting the size vector, iterate over that vector. W = 0.50, L = 3.00, C_I = 0.000000, L_series = 0.000001, R_series = 0.101980 Is A1 always evenly spaced? I'm assuming that the matlab matrix objects have more overhead and probably already assume that NaNs need to be accounted for. of arbitrary dimension, you can use arrayfun to apply my_func to each element: If A is a cell array of arbitrary dimension, you can use cellfun to apply my_func to each cell: The function my_func has to accept A as an input. How can I iterate through two arrays at the same time that have equal sizes ? There are about ~1000 elements in each array although each array is a different length from each other. however, I get following error: Index in position 2 exceeds array bounds (must not exceed 1). Please edit your question to add the complete output you are looking for in matrix form. for instant: So, I should have 16 results. @Danon second example works assuming arrays share length and element order. Can you make a number in a list/cell your index in Matlab? Based on your location, we recommend that you select: . For example, if you have a 3-by-4 matrix (with 12 elements), your inner loop will only iterate 7 times. @ITroubs added case for string based indexes, even though the example data in the question do not specify any need for this.

Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide. For example, if we wanted to square the elements of A (yes, I know there are better ways to do this), one might do this: There are many circumstances where the linear index is more useful. MATLAB allows you to use either a row and column index, or a single linear index. I didn't know this iterator and it's resolve my problem. Thank you all!

A2 will aways be larger than T1. Maybe there is a "vectorized" way to do it instead Also, if you wanted to recover the indices for some reason, you still could using these two simple commands: Indexing in 64-bit MATLAB does indeed correctly allow 64-bit subscripts. The "Range" variable i use for further processing (function parameter) within the for loop. .
