The code roots_qcq.f contains routines to solve

quadratics
ax2 + bx + c = 0
image 		cubics
ax3 + bx2 + cx + d = 0

with real or complex coefficients.
 



Please cite the relevant references if you publish a piece of work that use these codes, pieces of these codes, or modified versions of them. If you're nice, offer co-authorship of the publication. At best, you'll love these programs so much that you'll send great wads of cash to me.
