How to arrainge data to use streamline?
10 views (last 30 days)
I have data exported from a finite element software that I want to use in MATLAB to plot streamlines. The format is
where xc, yc and zc are (M-by-1) vectors of the coordinates of the nodes. vx, vy and vz are the components of the velocity at those coordinate locations.
The help for streamline says the X, Y and Z inputs must be monotonic, but my vectors are not sorted. I think if I sort them to satisfy the monotonic condition then they will not match the vx, vy and vz sorting, and since it is very unlikely they will all sort the same way, there is no way to keep them meatched to the vx, vy and vz.
How can I get my data in a form that streamline can use?
