Why lost original file?

I have trained trainnetwork. I save the workspace as a .mat file. When i called the load .mat file again, the data appear in my workspace. But program original file is lost. Why?

That could happen if you accidentally save'd on top of your .m file. You should make sure to save to a .mat file.

There's at least an outside chance there might be an autosave file copy of the m-file -- look for files whose extension is ".asv" in the location you saved the original m-file.

Check if the default preferences for autosave have been modified -- there's a secton on backup files under the Editor/Debugger section...

yes, sir, if you save the net to mat file，may be use save file.mat variable, such as save the cnn_model

save a.mat cnn_model

then load a.mat can get cnn_model

if just use

save a.mat 

it auto save all variable to mat, if use load to get them, we can use

load('a.mat', 'cnn_model')

to get the target
