Suppose I have the following plotting function:


How can I modify the function so that it can accept optional arguments like ContourStyle, AspectRatio that can be passed into the built-in ContourPlot?

You can use a BlankNullSequence to deal with the options, just like this following code

selfPlot[f_, opts___] := 
 ContourPlot[{Re[f[x + I*y]], Im[f[x + I*y]]}, {x, -2, 2}, {y, -2, 2},
selfPlot[#^2 Sin[#] &, ContourStyle -> {Red, Blue}]
