A genus-zero minimal surface with four catenoid ends.
To open a MinLab surface specification file, choose
"Files | Open MinLab File" from
the MinLab menu.
The Open MinLab File panel (File | Open MinLab File)
The MinLab panel (Controls | MinLab) is where you specify the input
for the minimal surface you want to compute. It has three pages:
- The Surface panel
is where the Weierstrass data and initial conditions are set.
(Controls | MinLab | Surface)
- The Parameters panel
is for specifying the associate family parameter.
(Controls | MinLab | Param)
- The Settings panel
is for specifying internal settings controlling the integrator.
(Controls | MinLab | Settings)
The "surface" page on the MinLab controls panel is where you specify
the Weierstrass or spinor representation for the minimal surface:
The Surface page on the MinLab controls panel (Controls | Minlab | Surface)
- The Weierstrass representation takes as input two meromorphic functions
g and f, and computes the minimal surface as
- Alternately, the spinor representation takes as input two meromorphic
a and b, and computes the minimal surface as
The syntax expressing the parametrizing functions g and f
(or a and b) is Mathematica-like;
see parser syntax for details.
Information about the parser syntax
for the functions g and f.
From the "param" page on the MinLab controls panel you can interactively
move through the associate family of minimal surfaces.

The Settings page on the MinLab controls panel (Controls | MinLab | Settings)
The "settings" page lets you fine-tune the integrator:
- integrator count -- how many integration steps the integrator
takes along the edge of each polygon making up the surface.
- init integrator count -- how many integration steps the integrator
takes along the initial line from the base point to the first point of the
