bool operator!=(const nml::mat3& lhs, const nml::mat3& rhs)

Return true if the two mat3 are different, else, return false.

The inequality between two mat3 is calculated this way:

\(\begin{bmatrix} lhs.x.x & lhs.y.x & lhs.z.x \\ lhs.x.y & lhs.y.y & lhs.z.y \\ lhs.x.z & lhs.y.z & lhs.z.z \end{bmatrix} \neq \begin{bmatrix} rhs.x.x & rhs.y.x & rhs.z.x \\ rhs.x.y & rhs.y.y & rhs.z.y \\ rhs.x.z & rhs.y.z & rhs.z.z \end{bmatrix} =\)

\(\small (lhs.x.x \neq rhs.x.x) or (lhs.y.x \neq rhs.y.x) or (lhs.z.x \neq rhs.z.x) or\) \(\small (lhs.x.y \neq rhs.x.y) or (lhs.y.y \neq rhs.y.y) or (lhs.z.y \neq rhs.z.y) or\) \(\small (lhs.x.z \neq rhs.x.z) or (lhs.y.z \neq rhs.y.z) or (lhs.z.z \neq rhs.z.z)\)

Example

#include "include/mat3.h"
#include <iostream>

int main() {
        nml::mat3 a(1.0f, 2.0f, 3.0f, 4.0f, 5.0f, 6.0f, 7.0f, 8.0f, 9.0f);
        nml::mat3 b(3.0f, 2.0f, 5.0f, 1.0f, 6.0f, 9.0f, 12.0f, 1.0f, 2.0f);
        bool c = (a != b);
        std::cout << c << std::endl;

        return 0;
}

Result:

1
