Iam beginner to matlab. Still learning it.Recently i have been asked to compute curl of three velocity components and plot its contour w.r.t circumferential angle along x-axis and radius along y-axis. The data u,v and w is pre-calculated by me as follows
u = V * Cos(beta) * cos(alpha); % V is velocity in m/s and alpha,beta are angles in radians
similarly
v = V * cos(beta) * sin(alpha);
w = V * sin(alpha)
Someone recently commented out saying that to enable mat lab's curl functionality my u,v and w data should be in Cartesian coordinate. I relied saying that though my initial data is in spherical coordinates(V,alpha,beta) but iam using coordinate conversion on u,v and w and transforming my data to Cartesian coordinate.
He further replied saying that "not only u,v,w should be Cartesian but its relative data x,y,z should also need to be Cartesian coordinate"
I dint get it. Can anyone say what he was trying to say or if i can use the curl functionality in matlab's.
(I further came across this Mupad interface page in matlab. Can someone please let e know if i can solve my problem using that/extending that interface)
I shall be grateful for your help and answer.
Thanks
