Writing code to evaluate B-form of the spline without using any built-in functions that directly give the B-form

Hello,

my task is to write a code to find out the B-form of the spline f given knots, degree of the polynomial, data sites x and data values y such that f(x(j)) = y(j) for all j . There is a function called 'spap2' which does exactly this, but I need to calculate the B-form without using it or any other built-in function which gives the B-form directly.

Good luck with that.

I should have been more clear while saying without using any built-in functions. Any other built-in functions are fine, but just those which compute the spline directly, I need to avoid those. Like spap2, spmak,etc.

In other words I need to simplify what 'spap2', 'spmak' does and write it in a code.

Okay, then what is your question? http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

Thanks for the links you have provided. As I told in the previous comment, I need to simplify spap2, spmak, i.e, I have to get the result of what spap2, spmak gives without using them. So my question is how to achieve this?

[Walter Roberson]

That sounds like a mathematics question, not a question about MATLAB.

Ok, thanks for your time.
