While it is not adviseable to have variables created in this way maybe you have a good reason to but still un-adviseable but here you go:
name_str = 'name_var';
eval(sprintf('%s = 5',name_str))
disp([name_str 'has been assigned to ' num2str(name_var)])

"...maybe you have a good reason..."
It is rather curious, that almost every time I ask for that specific "good reason" that some beginner insists that they have that requires them to dynamically name variables, either of these happen:
- it turns out that their data and/or code is very poorly designed (and someone shows them significantly improved code using simpler, more robust, much more efficient design concepts).
- they disappear from this forum without actually describing the specific "good reason" (or they just keep repeating "I must do this", without explaining why).
For the sake of my own curiosity, what is this mystery "good reason" ?
