• example : solve for root of a 5th order polynomial equation ```nim import gsl/gsl_poly import strformat

var i : cint a = @[-1.0, 0.0, 0.0, 0.0, 0.0, 1.0] z = newSeqcdouble

w = gsl_poly_complex_workspace_alloc(6)

discard gsl_poly_complex_solve(a[0].addr, 6, w, z[0].addr) gsl_poly_complex_workspace_free(w)

echo fmt"Roots for x^5 - 1 = 0" for i in 0 .. 4: echo fmt"z{i} = {z[2i]} + {z[2i+1]} i" * output Roots for x^5 - 1 = 0 z0 = -0.8090169943749477 + 0.5877852522924734 i z1 = -0.8090169943749477 + -0.5877852522924734 i z2 = 0.3090169943749475 + 0.951056516295153 i z3 = 0.3090169943749475 + -0.951056516295153 i z4 = 0.9999999999999999 + 0.0 i ```
