MATLAB: Basic math operations with numbers stored in cell arrays

Question

uitables are cell arrays and i can't do basic math with the data i get from the uitable , i tried cell2mat but it just concatenates all the numbers together as if they were strings and the division of a column by another gives wrong results

Answer 1

You probably have strings in the table and not numbers. If so, you should use STR2DOUBLE instead of CELL2MAT. It can operate on cell arrays and it outputs a numeric array.

 >> cell2mat( {'12', '34'; '54', '32'} )          % This is probably what happens.
 ans =
  2×4 char array
    '1234'
    '5432'
 >> str2double( {'12', '34'; '54', '32'} )        % This is what you should do instead.
 ans =
    12    34
    54    32
