get number of coloumns in array in matlab in matlab

To get the number of columns in an array in MATLAB, you can use the size function and specify the second output as the number of columns. Here's the code:

main.m
% Create an example array
array = [1 2 3; 4 5 6; 7 8 9];

% Get the number of columns in the array
numColumns = size(array, 2);

% Display the number of columns
disp(numColumns);
179 chars
9 lines

In this example, the array has 3 columns, so the output will be:

main.m
3
2 chars
2 lines

Note that the size function returns a matrix, where the first element represents the number of rows and the second element represents the number of columns. By specifying the second output 2, we are extracting only the number of columns.
