Ellipsis(float x, float a, float b, bool "up_part", float "xc", float "yc")


Returns the y-value of x so that the point (x,y) lies on an ellipsis defined by long axis half-length a, short axis half-length b and its center (xc,yc).

If xc or yc are not provided they default to zero.

up_part determines whether the point will be on the upper or lower part of the curve. If up_part is true or omitted it will on the upper part (ie >= yc), else on the lower (ie < yc).


TODO in a later version of AVSLib.
