Computes a p by p matrix describing parasite dispersal from infecteds (columns) to infectees (rows). $$\mathcal{Z} = e^{-\Omega\tau} \cdot \mbox{diag}\left( \frac{fq M}{W} \right) \cdot {\cal D} \cdot fq\Omega^{-1}$$

metric_calZ(Omega, tau, f, q, M, W, calD)

Arguments

Omega

the mosquito demography matrix

tau

duration of the extrinsic incubation period

f

the feeding rate

q

fraction of bloodmeals taken on humans

M

size of mosquito population in each patch

W

ambient human population at each patch

calD

parasite dispersal by humans matrix (see ramp.xde::metric_calD)

Value

a numeric matrix
