If you want to do make an implementation that supports runtime-specified matrix sizes you change your implementation from... auto *my_matrix = new MathArray<double, 10, 10>(); Into auto *my_matrix = new MathArray<double>(10, 10); Most programs don't need dynamically sized arrays (rows and columns) and as such it makes sense to also provide a template Row and Column width. By doing this you can likely implement matrix multiplication and addition as a constexpr (with some effort) and thus get.... 1. Compile time matrix evaluation 2. Vectorized multiplication/addition of matrices 3. Pipline-efficient code
