GRID:INTERPOLATE

SIZE

 Syntax: GRID\SIZE              s x y z m
         GRID\SIZE\XYOUT        s x y z m xout yout
         GRID\SIZE\BOUNDS       s x y z m           minx maxx miny maxy
         GRID\SIZE\XYOUT\BOUNDS s x y z m xout yout minx maxx miny maxy
 Defaults: \NOSIZE, s = 5*sqrt(min(len(x),len(y),len(z)))

 By default, the interpolated matrix will be square, with row and column
 dimensions both equal to 5*sqrt(min(len(x),len(y),len(z))). If another
 size, s, is desired, you must use the \SIZE qualifier, and the row and
 column dimensions will be both equal to s.

XYOUT

 Syntax: GRID\XYOUT               x y z m xout yout
         GRID\SIZE\XYOUT        s x y z m xout yout
         GRID\SIZE\BOUNDS\XYOUT s x y z m xout yout minx maxx miny maxy
         GRID\BOUNDS\XYOUT        x y z m xout yout minx maxx miny maxy
 Defaults: \NOXYOUT

 If output vectors, xout and yout, are desired, you must use the \XYOUT
 qualifier. The coordinates of output matrix element m[i,j] will be
 (xout[j],yout[i]), where xout contains the x-coordinates of each column
 and yout contains the y-coordinates of each row.

BOUNDS

 Syntax: GRID\BOUNDS              x y z m           minx maxx miny maxy
         GRID\XYOUT\BOUNDS        x y z m xout yout minx maxx miny maxy
         GRID\SIZE\BOUNDS\XYOUT s x y z m xout yout minx maxx miny maxy
 Defaults: \NOBOUNDS, minx=min(x), maxx=max(x), miny=min(y), maxy=max(y)

 By default, the range of the grid interpolation is the range of values
 of the vectors x and y. If the \BOUNDS qualifier is used, this range
 is specified by the final four numbers, minx, maxx, miny, and maxy.
