Calling a function inside of a another function.
what I would like to do is take
function x = fgIntersect(f, df, g, dg, x0, tol, maxIter)
and calculate the output x using another function,
function [r,rHist,N,fRoot] = newtonRaph(fHan,dfHan,x0,fTol,iterMax)
replacing fHan with h ( h = @ (x) f(x) - g(x)), and dfHan with dh ( dh = @ (x) df(x) - dg(x)).
so I would have:
function [r,rHist,N,fRoot] = newtonRaph(h,dfh,x0, tol,maxIter)
and the output of this function (newtonRaph), r is equal to the output of the previous function (fgIntersect), x.
No products are associated with this question.
So just calculate fHan by calling h(), and calculate dfHan by calling dh(), in advance of you calling newtonRaph(), then pass them in to newtonRaph(). It's a simple process.
