Hello I have a cubic equation with known arrays of X and Y.the number of arrays change between 10 t0 100. Now I need to get equation coefficients .
known x=>double[50]
known y=>double[50]
a*x^3+b*x^2+c*x+d -->a=?
b=?
c=?
d=?
Please guide me to use common math library to solve my problem.
Thank you in advance.
