回答： David Haydock 2022-1-12

I have an n x 1 cell array, and a list of indexes for this cell array that need to be used to insert new values into the cell array, at those given indexes. My problem is that as soon as I add a value at a given index, the length of the cell array is going to change, and then my next index is invalid.

How would I go about doing this? Any help would be appreciated!

Provide an example, please.

%Here is an example
% take some cell array
cell_arr = {'A', 'B', 'C', 'D', 'E', 'F'}
% and some set of indexes
idx = [1, 3, 4]
% I need to insert a value, '\n' in cell_arr at 1, 3 and 4.
% if I loop this, adding in '\n' at position 1 increases the size of the
% array by 1, and means that where I previously had to add '\n' to position
% 3, it would now be in position 4, and so on.
% I do not wish to replace the values at each of these indexes, but to add
% in values at these indexes.
