To fix this, you need to create an array of x_ values that isn’t linear but that produces points that are linear along the circumference of the orbit. As a point moves smoothly around a circular orbit, its projection on the x-axis moves (co-)sinusoidally, so you can fix this by ch...

Describe the bug I use the version 6.4.0-2D-c of ulab, which was built by myself to use on my rp2040 device. When I use numpy.where(condition,x,y) and pass a variable of type np.bool to the condition parameter, the code exhibits differen...

Presumably we need a size check to see if we'll hit this corner case and in that case choose a different protocol. Unless of course it's safe to just use the newer protocol always, but I suspect protocol 3 is hardcoded because of backward compatibility concerns. Copy link Author khood5...
