Fitting a linear sine curve with natural spline

I am relatively new to Matlab. The threads that I searched regarding the topic is in vain. Through core Matlab functions, kindly assist in fitting a linear sine curve(s(x)=sinx) between o and 2*pi with a natural and cubic spline. In terms of the natural spline, we can use condition: second derivatives at the two ends of the spline are set to zero. For cubic spline, we can use condition: Tangent direction of the cosine curve at the two endpoints to be the starting and ending tangent vectors.

So you search for an approximating spline for which you worry about the end conditions ? That's unusual. I guess that you will have to write your own code to implement such a speciality.
Best wishes
