function that deletes element from cell in matlab

To delete an element from a cell array in MATLAB, you can use the {} or () operator to access the element(s) that you want to delete and then assign empty brackets [] or {} to that element. Here's an example function that takes a cell array Cand an indexidx`, and removes the element at that index:

main.m
function C = deleteElementFromCell(C, idx)
% Removes an element from a cell array
    C{idx} = []; % or C(idx) = []
    C = C(~cellfun('isempty',C)); % remove empty elements from the array
end

To use this function, simply call it with your cell array C and the index of the element you want to remove:

main.m
C = {'apple', 'banana', 'cherry', 'dates'};
idx = 2;
C = deleteElementFromCell(C, idx);
disp(C)
% Output: {'apple', 'cherry', 'dates'}

In this example, the second element ('banana') has been removed from the cell array C.
