Hi all,

My file that worked with a thin matrix (with few rows and colums) finally
made an error but I can´t comprehed why?

 valor ausente donde TRUE/FALSE es necesario (absent value TRUE/FALSE is
necessary?)

Error en if (data[i, j] - last1[1, j] != 0) data2[i, j] = 0 else { :


You recommed to part the file of 4 Million rows x 13 colums?
