ComputingThe CMCLab notebook (Controls  CMCLab) is where you specify the input for the minimal surface you want to compute. It has four pages:
Potential PanelThe potential typically uses "z" for the surface parameter and "t" for the loop parameter. The syntax expressing the potential is Mathematicalike; see parser syntax for details. Initial Condition Panel
Use this window to modify the initial value for the system defining the surface. Integration starts at the point "zstart" in the domain (defined in the Domain panel) and takes as initial value the contents of this window. A blank value is taken to be the identity matrix. This window uses the same input format as the Potential panel above. Setting an initial condition is essentially the same as "dressing" the surface. Parameters Panel
These parameters control the speed/stability of the internal CMCLab algorithm. Changing these can cause CMCLab to malfunction. Polynomial precision sets the internal cutoff in computations involving lambda. A higher value means a more stable calculation, at the cost of speed. Values less than 30 can be unacceptably unstable. Values greater than 120 can be unacceptably slow. Basis length should be twice polynomial precision. Integration count sets how many integrations steps are performed for each step in the grid set in the domain. Settings Panel
Set the associate family parameter to a complex number with modulus 1. The normal shift parameter is by default 0. A setting of 1 draws the parallel CMC surfaces, and a setting of 0.5 draws the intermediate constantGaussiancurvature Ksurface. The mean curvature parameter effectively scales the surface.
