...While our focus is on high-order finite elements, the approach is mostly algebraic and thus applicable to other discretizations in factored form, as explained in the user manual and API implementation portion of the documentation. One of the challenges with high-order methods is that a global sparse matrix is no longer a good representation of a high-order linear operator, both with respect to the FLOPs needed for its evaluation, as well as the memory transfer needed for a matvec. Thus, high-order methods require a new "format" that still represents a linear (or more generally non-linear) operator, but not through a sparse matrix.

Freemat is an interpreted, matrix-oriented development environment for engineering and scientific applications, similar to the commercial package MATLAB. Freemat provides visualization, image manipulation, and plotting as well as parallel programming.

Python language bindings for the GtkExtra widget set. GtkExtra is a useful set of widgets for the GIMP Toolkit, aka GTK+. It provides a spreadsheet-like matrix widget and widgets for 2-D and 3-D graphing.

given three point that are not co-linear in the object or image space return a rotation matrix and offset that allows image points to be projected back into object space.

6Vertex is an Objective C/Cocoa application (and standard C functions) for computing and visualizing matrix models generated with the 6-vertex model for computing boundary shapes and phase transition shapes for differently weighted vertices.
