Create functions in the programming language

The concentration of a drug in the body Cp can be modeled by the equation: on-Do ka Cp = (k (ek - etet) Where Do is the dosage administrated (mg), V, is the volume of distribution (L), k, is the absorption rate constant (h ), k, is the elimination rate constant (h--), and is the time (h) since the drug was administered Create a function that bring as output the concentration of a drug in the body at time required. For a certain drug, the following quantities are given: De 150 mg, V = 50 L, k, = 0.4 h-4, ka = 1.6 h-1 Write as a function introduction in the comment space for help tool: The function input variables The function output variables The purpose of the function Add inside the function algorithm the command nargin Nargin (number of argument in), is very useful to verifying if the user enter the correct quantity of argument in the function. As example if the function need 3 argument add in the function: if nargin = 3 errordig('Not enough input arguments) end
