Calculating vertical velocity - dx and dy from kernel
Rather than taking midpoints, it looks like I can calculate dx and dy at the midpoint if I use a 3x3 kernel. e.g.
a b c
d e f
g h i
[du/dx] = ((c + 2f + i) - (a + 2d + g) / 8
[dv/dy] = ((g + 2h + i) - (a + 2b + c)) / 8
I...
Hello,
I'm working with a 2 x 3D arrays of fluid velocity values (east-west -> u and north-south -> v) and would like to properly calculate vertical velocities (w) from them (n.b. this is not homework). This ultimately needs to go into a processing algorithm, so while symbolic math is...
