A - is constant matrix, x - is constant vector. I there a problem in
linear algebra module???

the idea is simple yet realization is much harder.

by default f1(t),...,fn(t) - linearly dependent if there exist
coefficients x1,...,xn : x1^2+...+xn^2!=0
and x1*f1(t)+...+xn*fn(t)=0

if you choose n good points t0,...,tn you will have linear system Ax=0

the only problem is - to choose "good" points, but it is solvable.
