Math 218: Matrices and Vectors

Welcome! You have found the homepage of the Summer 2024 manifestation of Math 218.

Projections

The following code will calculate the projection matrix onto a space V after the user inputs a basis of V.

To project a vector v onto V, we use the matrix-vector product P*v.

The following code will take a matrix A and print data describing its four fundamental subspaces, including the projection matrices onto each subspace.
