TFINBLIN

 
Generates a two-dimensional boundary-fitted grid using transfinite bilinear
interpolation. Creates a curvilinear coordinate system that maps the unit
square onto a region whose boundary is input by the user. The boundary must be
divided into four sides: bottom, left, top, right. TFINBLIN maps the square to the
piecewise linear interpolant of the boundary obtained by connecting the
boundary points.
