 void functionSetvals(std::vector<float>&m, std::vector<float>&b)
{
		m[3] = 6; //arbitrary
		b[3] = 3;
		printLines(m, b);
}
void printLines(std::vector<float>&m, std::vector<float>&b)
{
	Std::cout << "Hello Universe"<<std::endl;
	Std::cout << m[3]<<std::endl;
	Std::cout << b[3]<<std::endl;
}

Main:
...
std::vector<float> m(4, 0.0f); // 
std::vector<float> b(4, 0.0f);
functionSetvals(m,b);
...

void printLines(std::vector<float>&m, std::vector<float>&b);

void functionSetvals(...)
{
    // ...
    printLines(m, b);
}

void printLines(std::vector<float>&m, std::vector<float>&b)
{
	// ...
}
