Calling an object dynamically in Matlab

Say I have the following variable

myClassName = 'myClass';

And I want to call an instance of the myClass constructor function, ie.

myObject = myClass(arg1, arg2, ..., argn);

Let's say I want to call it using myClassName.

myObject = (myClassName)(arg1, arg2, ..., argn);      % something like that

How do I do that?

Does the initial variable myClassName actually need to be a string? I would implement this as:

myClassName = @myClass;
myObject = myClassName(arg1, arg2, arg3);

This is pretty similar to using the str2func call from your selfanswer, bit without the string operations which make some people (for example, me) feel wrong.

eval can also be used:

eval([myClassName '(arg1,arg2,arg3)']);

Got it. I found that this:

myFunc = str2func(myClassName);
myClass = myFunc(arg1, arg2, ..., argn);

Does the job.
