BaseTDEMSimulation.Jvec(m, v, f=None)

Jvec computes the sensitivity times a vector

\[\mathbf{J} \mathbf{v} = \frac{d\mathbf{P}}{d\mathbf{F}} \left( \frac{d\mathbf{F}}{d\mathbf{u}} \frac{d\mathbf{u}}{d\mathbf{m}} + \frac{\partial\mathbf{F}}{\partial\mathbf{m}} \right) \mathbf{v}\]

where

\[\mathbf{A} \frac{d\mathbf{u}}{d\mathbf{m}} + \frac{\partial \mathbf{A} (\mathbf{u}, \mathbf{m})} {\partial\mathbf{m}} = \frac{d \mathbf{RHS}}{d \mathbf{m}}\]
