Length of a 3D curve.
28 views (last 30 days)
So I have created the code to calculate the length of a 3D curve which is:
function length_total = spacecurvelength(x,y,z,a,b,n)
% x, y and z are the curves
% a=lower limit b=upper limit n = number of straight lines used to approximate the curve length
% there are m-1 splines for m points
I am calling it with:
curvelength = spacecurvelength(@(s) 2*sin(s),3*cos(s)*exp(s),s.^2/10,-4*pi,pi,100)
But I'm getting the error
Undefined function or variable 's'.
