Hello,

I am working with matlab coding. I need to run the simulations for different models. For the 1st model, I run the simulation, it saves output in the workspace. but when i run the 2nd model, it saves the output file for the 2nd model. That is why i need to save the output for the 1st model to a file. So, i can store my outputs of all models.

can anyone please suggest me how to do?

it's showing error:

''Error using load

Number of columns on line 3 of ASCII file finaloutput.m must be the same as previous lines.''

Do not save naming .m file as destination . Name a .mat file.

You can save them in matfiles

"Don't forget to write '-append' at the end otherwise it will write the variables over your existing variables. Meaning that your old variables will be deleted."

Yet that is exactly what the -append option does for .mat files: it overwrites existing variables of the same name, which confuses a lot of beginners (it would be better named overwrite or something similar). This is explained in the save help (and easily checked with a few tests).

The suggested answer to use matfile is pointlessly complex for this trivial task. Much simpler to use save in a loop, generating the filename each time:
