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

vortz=vort3dord2(x_velocity,y_velocity,z_velocity,step)
