2curl
Purpose Computes the curl and angular velocity of a vector field
Syntax [curlx,curly,curlz,cav] = curl(X,Y,Z,U,V,W)
[curlx,curly,curlz,cav] = curl(U,V,W)
[curlz,cav]= curl(X,Y,U,V)
[curlz,cav]= curl(U,V)
[curlx,curly,curlz] = curl(...), [curlx,curly] = curl(...)
cav = curl(...)
Description [curlx,curly,curlz,cav] = curl(X,Y,Z,U,V,W) computes the curl and
angular velocity perpendicular to the flow (in radians per time unit) of a 3-D
vector field U, V, W. The arrays X, Y, Z define the coordinates for U, V, W and must
be monotonic and 3-D plaid (as if produced by meshgrid).
[curlx,curly,curlz,cav] = curl(U,V,W) assumes X, Y, and Z are
determined by the expression:
[X Y Z] = meshgrid(1:n,1:m,1:p)
where [m,n,p] = size(U).
[curlz,cav]= curl(X,Y,U,V) computes the curl z-component and the
angular velocity perpendicular to z (in radians per time unit) of a 2-D vector
field U, V. The arrays X, Y define the coordinates for U, V and must be monotonic
and 2-D plaid (as if produced by meshgrid).
[curlz,cav]= curl(U,V) assumes X and Y are determined by the expression:
[X Y] = meshgrid(1:n,1:m)
where [m,n] = size(U).
[curlx,curly,curlz] = curl(...), curlx,curly] = curl(...) returns
only the curl.
cav = curl(...) returns only the curl angular velocity.
Examples This example uses colored slice planes to display the curl angular velocity at
specified locations in the vector field.
