Save data to a subset of a variable y in the file myfile2 mat using the mat file object.

So when you save only one variable dataout the output of load is a structure with one field. Create and save two variables p and q to a file called pqfile mat. To save all workspace variables to a mat file on the home tab in the variable section click save workspace. You also can use command syntax to save the variables p and q.

At the end i should have 10x1000000 matrix in z mat and my variable out should hold only 1x1000000 vector during each iteration at a time. Save pqfile mat p q. This is exactly what load does when it has an output variable. This matlab function saves all matlab variables to the mat file filename.
