Reading from a Mat-File:

The load function is used to read from various types of files. As with save function, by default the file will be supposed to be a MAT-file, and load can load all the variables from the file or only a subset. For illustration, in a new Command Window session in which no variables have been generated yet, the load function could load from the files generated.

>> who

>> load sess2

>> who

Your variables are:

mymat x

The subset of variables in a file can be loaded by identifying them in the form

load filename variable list
