RECTGRID Generate 2D rectangular tensor product quadrilateral grid.
[ GRID ] = RECTGRID( N_CX, N_CY, XP ) Generates a tensor product quadrilateral grid with N_CX, N_CY cells in the x and y-directions, respectively. The optional argument XP=[x1 x2; y1 y2] specifies the coordinates of the lower left (x1,y1) and upper right (x2,y2) corners. N_CX and N_CY can also be vectors of x and y-coordinates. A call without input arguments generates a default 10x10 unit square.
grid = rectgrid();
grid = rectgrid( 20, 40, [-0.5 0.5; 1 2] );
grid = rectgrid( [0, 0.1, 0.4, 1], [0:0.25:1.5] );
