Alternative to 'eval', 'evalc','feval' etc functions in the Cody solutions

Why cody does not allow 'eval', 'evalc','feval' etc functions in the solutions? What is alternative to these functions?

e.g. I need to use:

if f='3*x'
x=0:10;
y=eval(vectorise(f))

so that values of y can be calculated as 3.*x

bt cody does not let us to use functions like eval

What is the alternative?

str2func() or inline()

[Swapnali Gujar]

inline() works, but that is also not allowed by Cody. str2func() doesnt work

[Walter Roberson]

matlabFunction(sym(f))

matlabFunction automatically vectorizes.
