Select entries of the matrix A using the sliders at right.

An "input vector" v is drawn in yellow in the graphing window, and the "output vector" Av is drawn in blue.

Control the input vector by dragging it in the graphing plane, by setting its rectangular coordinates using the sliders at left and below the graphing window, or by setting its polar coordinates using the [r] and [θ] sliders at bottom.
