Visualising row, column and solution spaces
This applet shows the row, column, and solution spaces of a 3x3 matrix M.melbapplets.ms.unimelb.edu.au/2023/02/01/visualisingrowcolumnandsolutionspaces

Columns of a matrix and the ranknullity theorem
This applet shows how the column space, solution space, rank and nullity of a matrix M change as you append additional columns. Initially the matrix M has a single column. You can add extra columns to M by editing the text boxes on the right of the applet, and clicking the ‘Append column’ button.

Linear transformations and eigenvectors
This applet illustrates the effect of a linear transformation in R2 on the unit circle/unit disk, and the geometric meaning of eigenvectors, eigenvalues and determinant.melbapplets.ms.unimelb.edu.au/2021/07/12/lineartransformationsandeigenvectors

Vector projections
This applet aims to demonstrate visually the projection of a vector u onto a vector v.
