Hi Dimitris and Walter,
actually, you don't need to use different variable names.
What you do is to first load the variable you want to
append something new to by load('myfile.mat','a'). Then
append your new values to the end of a, and then save it
using the -append option, save('myfile.mat','a', '-
append'). Note that you need a temporary variable name for
your new variable a, since the name of a in the mat-file
can't be changed when you load it.
