c++ general purpose multithreaded numerical vector class implements: operators, scalar vector aritmetics, several creators, memory mgr. seq, reverse, apply func, filters, . etc. uses kahan algorith to preserve precission when summing vector's components. samples:
VectReal vx(0, M_PI, 1e-4), vy(vx, sin), vytest=vx.func(sin); assert(vx.func(tan) == vx.func(sin) / vx.func(cos));
