How can I zscore a matrix

Hi everyone, I'm trying to do a zscore of a matrix but I'me having these errors. Error using var (line 65) First argument must be single or double.

Error in std (line 38) y = sqrt(var(varargin{:}));

Error in zscore (line 44) sigma = std(x,flag,dim);

How can I correct that? Thank you for your help.

If the argument to zscore is a cell array, use the cell2mat function to convert it to a double array before you pass it to the zscore function.
