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))
name_var = 5
disp([name_str 'has been assigned to ' num2str(name_var)])
name_varhas been assigned to 5

Hello!! Thank you very much for the answer,
Of course I can give the simplified context,
I have an excel file with some names and some related number codes, i will read the excel list and do some math operations with the code and then generate a "NAME_CODE.mat" file so i can email each pearson their files, no one can have access to another person file.

@Victor Andrés Sánchez Zurita: nothing in your description requires dynamically named variables.
Most likely this is a complex and inefficient approach to processing your data.
