Detailed Description

derivative calculation of y=f(x) : dy/dx

---

dydx = ITM_derive(x,y,c0,c1,d,o); input x = radial coordinate y = function to derive

---

c0 = boundary condition at the center scalar for dy/dx 0 -> = 0 1 -> use two points for the center value 2 -> prolongation for d2y / dx2 0 -> d2y/dx2 = 0 1 -> dy/dx = 0 2 -> prolongation

---

c1 = edge boundary condition (idem c0 for the edge)

---

d = dimension of the derivation

---

o = order of the derivation (1 ou 2)

---

output

dy / dx sample

x=0:pi/2 y=cos(x) dydx = ITM_derive(x,y,0,1,2,1) dydx = -sin(x)
