How can I write code for cubic spline interpolation?

Hello

I need to realize a cubic spline with some constraints

But I could not generate code for cubic spline interpolation

Although I can handle the curve fitting tool, but when I use that tool, I could get only the roughly drawn spline

Anyway, the condition of spline interpolation that I want to generate is written below.

I prepared the link that contains the spline interpolation that I want to generate

Please focus on the Appendix B

Although I can make the equations of each spline, but how can I generate those interpolations?

I will be very appreciate when you answered to my questions

Thank you for reading this.

PS. I want to write codes on this article if I wrote anything, but I could not.

I`m very sorry for this poor works and article.

The article is behind the IEEE paywall. Many of us do not have access to it.

As one of the people who COULD help you, I won't go through a paywall to read your question. That is inappropriate to ask of anyone.

I will point out that my SLM toolbox (on the file exchange) already exists as a spline with a huge variety of constraints. So you MIGHT very possibly need to write absolutely nothing at all. That I cannot know since you have not bothered to ask your question in a form that can be read.
