name = 3 ;
name = 'John' ;
That's it....why you want to assign again a ? This approach is not accepted.

John = 3 ;
This is enough right.

Before you force yourself into writing slow, inefficient, complex code that is difficult to debug, you should read this:

a = 'Pi';
val = pi;
eval(a + " = " + val);
This link has some alternatives to using string evaluation to run code. It's a bad/dangerous style and there's almost always a better approach.
If you must name your variables with another variable, consider using fields of a struct rather than raw variables:
mydynvars=struct;
a = 'Pi';
b = 'e';
mydynvars.(a) = pi;
mydynvars.(b) = exp(1);
mydynvars
