MATLAB: How to remove the first 5 characters from a cell array 343×1 cell

removing characters from a cell array

Hello all, I would like to remove the first few characters from every single cell (343), yet I am not much aware of how to do it. I tried to solve the problem via googling it yet could not find anything that would fit my case. The cell array is attached. Example: for "d035-117" for instance i would like to convert it into a form of "117". The first 5 characters need to be truncated. Thanks for your advices and help in advance!

How about (untested)

for k = 1 : length(ca)
    cellContents = ca{k};
    % Truncate and stick back into the cell
    ca{k} = cellContents(6:end);
end

MATLAB: Combine each 8 matrices in a cell array

How about just a loop? Assuming a 1-D cell array

caOut = cell(length(ca)/8, 1); % New cell array for the output
counter = 1;
for k = 1 : 8 : length(ca)
    % Put 8 cells of ca into one cell of caOut.
    caOut(counter) = {[ca{k}, ca{k+1}, ca{k+2}, ca{k+3}, ca{k+4}, ca{k+5}, ca{k+6}, ca{k+7}]}
    counter = counter + 1;
end

MATLAB: Cell array to string array

Something like this

A = {'Hello B Hi A Where is D?'};
B = strsplit(A{:}, ' ')';

Result:

B =
  7×1 cell array
    {'Hello'}
    {'B'    }
    {'Hi'   }
    {'A'    }
    {'Where'}
    {'is'   }
    {'D?'   }
