What software can I use to visualize transformations of the plane?

  1. Jan 26, 2014 #1
    For example, I would like to visualize the transformation

    u=cot-1(1/α y/x)

    mathematics packages:
    matlab, maple, maxima, octave, scilab
    graphics packages:
    tecplot, gnuplot.

    There are probably dozens (hundreds?) more, but these are the ones I use.

    Thanks! Are any of those free?

    you have to pay for tecplot, matlab and maple, but if you are a student then your university might get you a discount.
