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)
