hi,

can i refer to a variable whos name is stored in another varialbe?

e.g. :
MyVar = [1 1 1];
a = 'MyVar';

Can i get to the values stored in MyVar using only the "a" variable?

thanks

Yes you can but it is not recommended :
help eval
example :
value2 = eval([a,'(2)']);

Caroline is right. You might want to consider changing your
application to make use of MATLAB structures - their fields can be
accessed dynamically by name (see "Programming and Data Types:
Structures and Cell Arrays: Accessing Data in Structure Arrays" in the
MATLAB help).
