Why cant't I save an array?

I'm trying to save a 1063x1 double called ewa to a file with this line of code:

    save(ewa.mat, ewa);

I get this error: Attempt to reference field of non-structure array.

Answer 1

[José-Luis]

 save('ewa.mat', ewa);

Thanks for your help!

There's now a different error. It says "Argument must contain a string."

[José-Luis]

 save('ewa.mat','ewa');

Sorry about that, I need some coffee. Please look at the documentation.

 doc save

[Joseph Cheng]

have you looked at the documentation for save? they have examples on its use.

The documentation shows that both inputs should be a string.

   save('ewa.mat', 'ewa');
