You wrote a function with the variable name in the definition line but never assigned a RHS to it.

SOTOO

function ab = yourfunctionname(x)
  % does what it does

    z=x.^1.5;
  end

As is easily seen, ab is never defined. ( z should have been ab or vice versa). Fix the similar problem appropriately in your function.
