## Description

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.

Examples
1) A 10x10 grid on the domain spanned by [ 0..1; 0..1 ]
  grid = rectgrid();

2) A 20x40 grid on the domain spanned by [ -0.5..0.5; 1..2 ]
  grid = rectgrid( 20, 40, [-0.5 0.5; 1 2] );

3) A grid spanning [0, 0.1, 0.4, 1], [0:0.25:1.5]
  grid = rectgrid( [0, 0.1, 0.4, 1], [0:0.25:1.5] );
