vort3dord2
algorithm
- vorticity measures the tendency of a vectorfield to rotate around a point
- calculates vorticity of a vector field components around x-, y- and z-axis in each point of the field
- uses second order gradients of Matlab
syntax
vortz=vort3dord2(x_velocity,y_velocity,z-velocity,step)
example for input
