Instructions:

$1.$ Create using MATLAB

$2.$ Use the following case:

The concentration of a drug in the body $Cp$ can be modeled by the equation:

$Cp=\frac{D_G}{V_d}\frac{k_a}{(k_a-k_e)}(e^{-k_{e}t}-e^{-k_{a}t})$

Where $D_G$ is the dosage administrated $(mg),V_d$ is the volume of distribution $(L),k_e$ is the absorption rate constant $(h^{-1}),k_a$ is the elimination rate constant $(h^{-1}),$ and $t$ is the time $($h$)$ since the drug was administered. For a certain drug, the following quantities are given: $D_{G}150mg,V_d=50L,k_e=0\mathrm{.}4h^{-1},k_a=1\mathrm{.}6h^{-1}$

Create a program editor that use while$-$loop prints in a single graph the function of sine

a$)$ A single dose is administered at $t=0.$ Calculate and plot $Cp$ vs $t$ for $10$ hours. Hint: to get a smooth graph use $0\mathrm{.}1$ as time interval

b$)$ A fist dose is administered at $t=0,$ and subsequently four more doses are administered at intervals of $4$ hours $($i$.$e$.$ at $4,8,12,$ and $16).$ Calculate and plot $Cp$ vs $t$ for $24$ hours. Hint: use continue command in this case.

c$)$ Build the flowchart that represent the program.
