|void polcurve (r, theta, dim, sym)||POLPLT.C||Level 3|
|float *r||The values of the radius vector.|
|float *theta||The values of the angle in radians.|
|unsigned dim||The dimension of the r and theta arrays.|
|int sym||= 0 To draw the curve only.
= > 0 To draw the curve and symbols every sym points.
= < 0 To draw symbols only every sym points.
|polcurve() draws a curve corresponding to the vector r,
on a polar grid. If r is logarithmic, the previous call to
polgrid() will provide cropping for the curve at the minimum circle.
