nml::mat2 operator*(float lhs, const nml::mat2& rhs)

Return a mat2 that is the product between a scalar and a mat2.

The product between a scalar and a mat2 is calculated this way:

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

Example

#include "include/mat2.h"
#include <iostream>

int main() {
        nml::mat2 a(1.0f, 2.0f, 3.0f, 4.0f);
        nml::mat2 b = 3.0f * a;
        std::cout << nml::to_string(b) << std::endl;

        return 0;
}

Result:

[[3.000000, 6.000000], [9.000000, 12.000000]]
