I have two variables:Var1=[1 2 3] and s='myData'. I am using assignin('base',s,Var1) to assign the contents of the text file as Var1 name. now I have another variable, myData=[1 2 3]. I wonder how I can save Var1 with the new name. Please let me know if I didn't ask it clearly.
Var1=[1 2 3]
s='myData'
assignin('base',s,Var1)
%now I have another variable, myData=[1 2 3] %now I want to save it with the new name with using the contents of s variable.
Save('C:\myData',assignin('base',s,Var1))

Hi Hassan,
If you are trying to name your data you can do it using eval function as follows, FOR eg: T=[1;2;3;4;]; and you want to name this as 'testmatrix' then eval(strcat('testmatrix','= T;'));
you can do the same where T can be struct or a file etc.. Hope this helps.

thanks Krishna for the comment. I didnt know about eval() but it seems it does the same as assignin().
