The numeric data in a line is separated by a. Ok you could theoretically store some limited metadata in the header of a version 5 mat file. I have a question on how i can add headers to a data matrix. I m new to matlab so i m not sure if i need to use the fprint function or if i need to change from csv to another format to make this easier.

Hi i have a text file with header i need to import the file to matlab and to use numeric data. If you are trying to save to a text file with column headers then really the best way is to fopen fprintf the headers fprintf the data and then fclose.
