MATLAB: String to Variable conversion

type conversion

So first I declare some variables:
   data.variable=12
   v1='variable'
   n=1
The results:
strcat('data.', v1)
    data.variable
But
strcat('data.', (strcat('v',num2str(n))))
  data.v1
Instead of data.variable. I'm assuming that this is because v1 is a string. What should I do to make the second command return data.variable?

You might find dynamic field names useful. Doc says:
    Generate Field Names from Variables
    [...] 
    For example, create a field name from the current date:
    currentDate = datestr(now,'mmmdd');
    myStruct.(currentDate) = [1,2,3]
