Does anyone know how to control the slope (or end tangency) of a pspline or cspline curve? I'm using MathCad 15.
I want to input definition points (using x and z vectors) to create a spline equation z(x). The part I'm having problems with is trying to force the spline to have zero slope at the definition points. I've attached a sheet to help with the explanation. Any ideas?
In case this might help, I'm writing the sheet to evaluate a post-tensioned concrete beam with multiple spans. The function will be used throughout the sheet to define the tendons.
Solved! Go to Solution.
Yeah, I think that does what I want! It is a bit of a cheat, but it seems as if MathCad doesn't have any built in functionality with the spline functions.
I noticed that lspline (linear end points) pushes the curve closer to 0 slope at the definition points.
Thanks for the help.
