Genius can also plot surfaces. Select the Surface plot tab in the
main notebook of the Create Plot window. Here you can specify a single
expression which should use either
y as real independent variables
z as a complex variable (where
x is the real part of
y is the
imaginary part). For example to plot the modulus of the cosine
function for complex parameters,
you could enter |cos(z)|. This would be
equivalent to |cos(x+1i*y)|.
See Figure 5.
For plotting using the command line see the documentation of the
