R Randomize matrix

H Toggle help panel

C Clear custom vectors

1-7 Load presets (Rotation, Scaling, Shear X/Y, Reflection, Projection, Squeeze)

Scroll wheel - Zoom in/out

Click & drag on canvas - Draw custom vectors

Drag eigenvector tips - Reconstruct transformation matrix

Hover over eigenvectors - See scaling information

Eigenvectors - Cyan and pink vectors that maintain direction during transformation

Determinant visualization - Shows area scaling factor (det = λ₁ × λ₂)

Randomize - Generate random transformation matrices

Custom vectors - Draw your own vectors to see how they transform

Animation speed - Control transformation speed (0.5×, 1×, 2×)

Eigenvectors only scale (stretch/compress), they don't rotate. Yellow test vectors show typical transformation behavior for comparison.
