Hi. I have this cell:
A = {'5';'11'};
B = {'7';'19'};
out = [A,B]; % cell 2x2
I should go from an 'out' cell 2x2 to an 'out' cell 2x4, where the missing columns (columns 3 and 4) are null cells:
empty_cell = cell(2,1);
The total number of columns in the 'out' cell should be imposed by:
parameter = 4;
So, the end result I want to get must be this:
empty_cell = cell(2,1);
out = [A,B,empty_cell,empty_cell]; % cell becoming 2x4 (where 4 is 'parameter')

Ran in:
No loop, no concatenation required:
A = {'5';'11'};
B = {'7';'19'};
out = [A,B]; % cell 2x2
parameter = 4;
out(:,end+1:parameter) = {[]}
out = 2×4 cell array
{'5' } {'7' } {0×0 double} {0×0 double} {'11'} {'19'} {0×0 double} {0×0 double}

You can simply add empty columns in a loop.
Given out and parameter are defined (out can be a cell of any shape, need not be 2x2),
% Calculate the number of empty columns to be added
num_empty_cols = parameter - size(out, 2);
Then, create an empty cell array with the same number of rows as 'out'
empty_cell = cell(size(out, 1), 1);
Finally add these cells in a simple loop:
for k = 1:num_empty_cols
out = [out, empty_cell];
end
Hope this helps!
