Interactive element. An interactive linear transformation sandbox. Select a matrix entry by clicking on one of the blocks to the right, then adjust the value with the slider below. Observe how different transformations emerge on the left.

Linear transformation

The connection between the entries of a transformation matrix A and the resulting linear transformation Ax can sometimes be a bit unintuitive. Here,

Here, I provide a small sandbox for D=2 and N=100 that may help building some intuition.
