# Coding contour integration [duplicate]

I am struggling to understand contour integration. How would it be applied in Mathematica? I am hoping that if I see it written in Mathematica code, it will help me understand it. eg how would $$\int_\gamma \text{}(z) = \int_a^b \text{f}(z(t)) z'(t) \, \text{d}t$$ be coded? (Example taken form Wikipedia.)
• It's basically a line integral of a scalar function of two variables along a path, $\gamma$ in your case. Do you not understand what it is conceptually or practically? – acl May 28 '14 at 20:29
