I can't figure out what it is that I'm doing wrong. eval() always returns with the same error, even in the simplest of executions.

>> d = eval(ns,'+',xs)
??? Index exceeds matrix dimensions.
>> eval('1/2')
??? Index exceeds matrix dimensions.

Some guidance will be appreciated.

something like this:

>> ns=int2str(17)
>> xs=num2str(18)

eval() can only take a single argument

>>> eval('1/2')
> ??? Index exceeds matrix dimensions.

That suggests that you have a variable named 'eval'.
