MATLAB: Cannot load data to matlab

Question

I have a file ARG_1. It is just a cell array that I have previously calculated.

Now I just want to load it:

load ARG_1

but I get the error:

Error using load

Unable to read file 'ARG_1'. No such file or directory.

Error in DATA (line 18)

load ARG_1

BUT IT DOES EXIST, and I can load it manually by clicking on the file as any other. It is in the same folder, so that is not an issue, don't know whats wrong.

Answer 1

It may need the extension as well:

load ARG1.mat

or:

load('ARG1.mat')

.
