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