use strings to give commands

Hi everyone,

I have many variables with different names and they all content a struct "Value". Now a program loads one of those variables in my workspace, only knowing by a string which one it is.

For example: str='xxx'; load('blabla.mat', str);

Now I want to get access to xxx.Value and I want to ask you, how I can get that command when I only have 'xxx' as a string?

As I told you, the program must being kept general, because xxx can stand for any of many variables.

Best regards and thank you! Oli

how about replacing

load('blabla.mat', str);

with

data = load('blabla.mat', str);

Then the variable can be accessed with

data.(str)
