Question

eval() returns the same error, even with the simplest of inputs.

>> ns=int2str(17)
>> xs=num2str(18)
>> d = eval(ns,'+',xs)
??? Index exceeds matrix dimensions.
>> eval('1/2')
??? Index exceeds matrix dimensions.

Any help would be appreciated.

try clear all first.. it seems you have a variable called eval that is shadowing the function.

>> eval = 1;
>> which -all eval
eval is a variable.
built-in (C:\Program Files\MATLAB\R2010a\toolbox\matlab\lang\@char\eval)  % Shadowed char method
C:\Program Files\MATLAB\R2010a\toolbox\matlab\lang\@opaque\eval.m         % Shadowed opaque method
C:\Program Files\MATLAB\R2010a\toolbox\stats\@classregtree\eval.m         % Shadowed classregtree method
