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

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
