Elementary dilation operator

• Vector $\mathbf w$ defining linear functional $\mathbf w^{\scriptscriptstyle\mathsf{T}}$ (move this by dragging the head of the arrow)
• Vector $\mathbf z$ NOT in hyperplane $\operatorname{NS}(\mathbf w^{\scriptscriptstyle\mathsf{T}})$ (move this by dragging the head of the arrow)
• Scale factor $c$: -2.0 -1.5 -1.0 -0.5 +0.5 +1.0 +1.5 +2.0
• Dilation operator is $M = I + (c-1) \frac1{\mathbf w^{\scriptscriptstyle\mathsf{T}} \mathbf z} \mathbf z \mathbf w^{\scriptscriptstyle\mathsf{T}}$
• Input vector $\mathbf v$ (move this by dragging the head of the arrow)
• Output vector $M\mathbf v$ (automatically computed for your convenience)
