Complex Function Plotter

With this app you can plot and save complex functions. The encoding of hue and brightness can be chosen individually. (Real part, imaginary part, argument and radius are possible)
The following functions are supported:
* abs() Absolute Value
* arg() Argumentfunction
* cos() Cosinusfunction
* Im() Imaginary part
* ln() natural Logarithm
* Re() Real part
* sgn() Signumfunction
* sin() Sinusfunction
* gamma() Gammafunction
* zeta() Zetafunction
* xi() Xifunction
* erf() Error function
You can also use ^ to exponentiate.
ATTENTION: gamma(), zeta(), xi() and erf() are computationally intensive! Computation will take some minutes to hours, depending on the device!


Notes for usage:
* Functions are calculated from -3 < Re(z) < 3 and -3 < Im(z) < 3 by default. You may change that by pressing the button "Change range"
* You can save function images by clicking the button "Save"
