I'm pretty sure you can do this with other logic, but the main reason we create that matrix with 0 values first is because in the for loop, you have: xbezier = xbezier + something. You need xbezier to be declared beforehand. The reason we populate it with zeros, is that since we are adding stuff to xbezier every loop, an initial value of 0 will not change anything. If we were multiplying, we would use 1s instead. Hope this helps.
Ya, by the way thank u for video, I was trying to hard code for b spline after coding all intervals ,I was not able to get or understand that basis function for different values of u.. How and what...... Please I beg u do a video on B spline hard code in python.. Because I am m tech student. I want doing projects on IGA SO I need to do it... And if have any video or materials of calculation of b spline do suggest.
@vasanthkumarkallannavar7594 I'm preparing a series of videos for B-splines, but is a tough concept to grasp, so as soon as I get it working I'll post it.

my profesor couldnt explain it in 1.5h, and you did that in less than 10 minutes, great job
This is beautiful...
@ 3:27 why creation of matrix of zero, can we skip it? use other logic there?
