Visual Complex is a graphing calculator to create a graph of complex function. 3D function graphs and 2D color maps can be created with this grapher. You can input complex functions in the form of w=f(z) (where z=x+yi) directly before creacting graphs. Graphs can be copied and saved in the format of bitmap.Complex Grapher is a graphing calculator to create a graph of complex function. 3D function graphs and 2D color maps can be created with this grapher.
