Saving Data from the Workspace
To save data from your workspace, you can do any of the following:
• Copy from the MATLAB Command Window and paste into a text file.
• Record part of your session in a diary file, and then edit the file in a text
editor.
• Save to a binary or ASCII file using the save function.
• Save spreadsheet, scientific, image, or audio data with appropriate function.
• Save to a file using low-level file I/O functions (fwrite, fprintf, ...).
For more information: See Saving the Current Workspace in the MATLAB
Desktop Tools and Development Environment documentation, “Using the
diary Function to Export Data” on page 6-87, and “Using Low-Level File
I/O Functions” on page 6-103.
Loading Data into the Workspace

of the following:
• Enterorpastedataatthecommandline.
• Create a script file to initialize large matrices or data structures.
• Read a binary or ASCII file using load.
