Generate a MatLab code that allows you to calculate the head loss $($hL$)$ and pump power in a generalized way, i$.$e$.$ for any number of accesories and pipe lengths. Head loss

$h_{L,\text{t}\text{o}\text{t}\text{a}\text{l}}=(f(\frac{L}{D})+{\displaystyle \underset{?}{\overset{?}{}}}{K}_L)\frac{v^2}{2g}$

I need $itto$ calculate the $kLas$ well, asking for the accesories
