Download Argand 32bit executable (updated Apr 28, 2022) Download Argand 64bit executable (updated Apr 28, 2022) Argand is a program for displaying transformations of the complex plane. An initial circle or rectangle in the complex plane (the zplane) is transformed by one of a number of possible functions w = f(z) from a dropdown menu, to obtain a new figure in the wplane. The wplane can also be transformed, and so forth. But with successive mappings, errors can easily occur. There are still some bugs, however I am releasing it asis, with no guarantees. It is for experimenting with functions in the complex plane. Executables for 32bit Haiku and 64bit Haiku are provided. Some screenshots are shown, mapping the circle of the first diagram into w=sinh(z), w=sqrt((za)(zb)), and w=sin(sqrt((za)(zb))). The data window with the constants a and b is also shown.
When the output of a multivalued function is transformed, the transformation is done only to one of the connected domains.
