DCL:GRPH2:UGPACK: Vector Field Display Routines: Explanation of Subroutines
Draws a 2-D vector field.
CALL UGVECT(U,MU,V,MV,NX,NY)
U (R) A MUnNY 2-D array giving the X component of a vector. The NXnNY portion is used for drawing the vector.MU (I) The first adjustable dimension of array U. V (R) A MVnNY 2-D array giving the Y component of a vector. The NXnNY portion is used for drawing the vector. MV (I) The first adjustable dimension of array V. NX (I) The first adjustable dimension for the array U, V used for drawing. NY (I) The second adjustable dimension for the array U, V used for drawing.
