I want to do the following in MATLAB:

dang = 1000;
jam = 'dang';
groo = str2var(jam);

This should give me groo = 1000. How do I do this?

Reason: I have a workspace that contains large integer array variables named like this: var1, var2, ..., var4500. I want to be able to use an iterative method to generate the variable names and the only way I can think of doing this is by concatenating strings in a for loop ('var' 'number'), and using those strings as variable names.

    You would need eval for that. But it's bad practice. As it is having separatte variables var1, var2 etc. Use a numeric array or a cell array instead Commented Sep 18, 2014 at 22:27
  • you can also use a structure with dynamic field. As an example: for ii=1:10 ; MyStruct.(['var' num2str(ii)]) ; end, but you can build the string the way you like. Look at the Matlab doc generate-field-names-from-variables. Your question has already been asked though, you can lookup the different answers here Commented Sep 18, 2014 at 23:16
  • Correct me if I am wrong, but eval lets me convert a variable into a string, not the other way round. Yeah, using a structure may be the way to go. Commented Sep 25, 2014 at 14:14
