Saving a 1x2 structure with 5 fields

I am trying to save my structure that I've called "mymat" in the workplace area as a file. When I try to save it like:

>> save ('mysummat.mat', '-struct', 'mymat');

I get the error message:

Error using save

The argument to -STRUCT must be the name of a scalar structure variable.

When I try to save it like:

>> save ('mysummat.mat', 'mymat')

I get the error message:

Error using save

Unable to write file mysummat.mat: No such file or directory.

I just want to be able to save this structure array specifically.

Never use the name of an inbuilt function to name your own function or variable

This means you should never use sum, length, mean, size, i, j, etc, etc.

This will only cause untold heartache and hard to diagnose problems. Use which to check names before you use them.

First, avoid using sum as a variable because it's a built-in Matlab function

som.a=4
som.b=5
save ('mysum.mat', '-struct', 'som')

I still get the error: Error using save

The argument to -STRUCT must be the name of a scalar structure variable.

Post the code you tested

Ok, then try this

som=struct('a',{1 2},'b',{3 4})
save ('mysum.mat', 'som')

I just want to save the entire structure that's called mymat in the workspace as a file. Is this possible?

 save('myFileName.mat','mymat')
