Complex Function Grapher

A tool to graph complex functions on the Argand plane (x + iy).

Description

-Graphs user-inputed functions of a complex square input array
-Helps with visualization of complex numbers and complex functions
-User gives limits (e.g. [-3,3] and [-3i,3i]) of the input square array and the number of points between the limits
-User provides title of graph, and can link inputs to outputs with lines
-Inputs shown as blue dots of the square input array; outputs shown as red dots
-Marker size adjustable
Inspired by Kaelyn Willingham and developed by Jon Moller

• MATLAB release: MATLAB 7.8 (R2009a)

Could be very useful if you turn the script into a function and allow command-line inputs (e.g. with function handles) to avoid having to retype the inputs interactively; also show which parameters and additional commands produced the example in the screenshot.
