Question

Problem 6. MATLAB PROBLEM: Plotting scalar functions of complex variables Given the function f(z) = with complex variable input z = x + jy, create a contour plot in Matlab/Octave that has Re(z) as the x-axis, Im(2) as the y-axis, and f(2)Plot it for the range -2 < Re(z) < 2 and -j2 < Im(z) < j2, with at least a grid of 100points for each axis (hint: use lin space, mesh grid, and surf functions in Matlab). Why does this contour plot only appear to have one asymptote, or problematic point?
