Simulation3DCurrentDensity.Jvec(m, v, f=None)[source]#

Jvec computes the sensitivity times a vector

$$\mathbf{J}\mathbf{v}=\frac{d\mathbf{P}}{d\mathbf{F}}(\frac{d\mathbf{F}}{d\mathbf{u}}\frac{d\mathbf{u}}{d\mathbf{m}}+\frac{\partial \mathbf{F}}{\partial \mathbf{m}})\mathbf{v}$$

where

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