    What are the differences between arrays and matrices?

    I mean when using them in terms of places and just using them with numbers, they seem pretty similar to me


    Thanks in advance.

    Well an array is a matrix extending in a single line. So given a single index, we can locate any spot in the array. If you lay many layers of arrays you could then describe 3D space with 3 coordinates (x, y, z). // ie: array[x][y][z] = value;
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
