[image] = MakeSineImage(freqi,freqj,nRowPixels,[nColPixels],[centerRowPixel],[centerColPixel])

Computes a two-dimensional sine function image.

The image has dimensions nRowPixels by nColPixels.
If nColPixels is omitted, a square image is returned.

If you want to pass centerRowPixel, you must pass nColPixels.
centerRowPixel and centerColPixel each default to zero if not passed.

8/15/94 dhb Both row and column dimensions used if passed.
dhb Changed zero frequency convention.
6/20/98 dhb, mw Fixed error in zero handling case.
9/07/23 dhb Allow passing of center row and column pixels,
leaving previous behavior unaffected
