Cardiovascular mechanics:

Write a MATLAB m$-$file to compute ventricular elastance using the given equation. Compute and

plot $E_v(t)$ for the parameter values in Example $2$ of this manual.

$E_v(t,V_v)=2a(V_v-b)+c[\frac{(1-e^{-(\frac{t}{{}_c}{)}^{}})e^{-(\frac{t-t_b}{{}_r}{)}^{}}}{(1-e^{-(\frac{t_p}{{}_c}{)}^{}})e^{-(\frac{t_p-t_b}{{}_r}{)}^{}}})$

$\begin{array}{cc}\text{Q}\text{u}\text{a}\text{n}\text{t}\text{i}\text{t}\text{y}& \text{H}\text{u}\text{m}\text{a}\text{n}(adapted)\\ a& 0\mathrm{.}0007\\ b& 20\mathrm{.}0\\ c& 2\mathrm{.}5\\ d& 80\mathrm{.}0\\ {}_c& 0\mathrm{.}264\\ t_p& 0\mathrm{.}371\\ {}_r& 0\mathrm{.}299\\ t_b& 0\mathrm{.}258\\ & 2\mathrm{.}88\end{array}$
