i want to do the conversion cell2mat, but the problem is that the guy that i want to convert has '[]' empty components in some cells, and numeric data in the rest of them, so i have this error:

All contents of the input cell array must be of the same data type

i cannot change the '[]' for 0 because i need to read 0 as number. so if anybody has a solution for this please help,

thanks a lot!

How about replacing [] with NaN?
A = {1 [] 2 3 [] 4 5};
A(cellfun('isempty',A)) = {NaN};
cell2mat(A);
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
ans =
1 NaN 2 3 NaN 4 5
