add something to a cellarray in matlab

To add an element to a cell array in MATLAB, use the curly braces and specify the index where you want to add the value. Here is an example:

main.m
% create cell array
myCellArray = {'apple', 'banana', 'orange'};

% add an element
myCellArray{4} = 'grape';

% display cell array
disp(myCellArray);
150 chars
9 lines

Output:

main.m
    'apple'    'banana'    'orange'    'grape'
47 chars
2 lines

This will add the value 'grape' to the end of the cell array. If you want to add the value at a specific index, just replace 4 with the desired index.

Note that if you try to access an index that does not exist in the cell array, MATLAB will automatically expand the size of the array.
