How to save uint8 workspace data

Hi, does anyone know how to save a uint8 workspace data to a external file, preferably text or binary file. I tried using : save zipped.txt zipped -ascii, but command window displayed Warning: Attempt to write an unsupported data type to an ASCII file. Variable 'zipped' not written to file.

Looks like your data is a cell array.

Convert them matrix using cell2mat and then use the save command

Or use dlmwrite

What representation do you need in the output file? If you want the value as simple text numbers, double() the uint8 data and save the double()'d value. Or use dlmwrite or fopen() / fprintf() / fclose() with the original uint8 data. If you want binary output, fopen() / fwrite() / fclose()
