Store input values in a javascript array

I am creating a matrix with dynamic input values. The program asks you for the order and the set of vectors. From that, it generates a bidimensional arrangement (with the values that you entered in the inputs, of course). For example, if I want to order 3 and 3 sets of vectors, the program creates the inputs so that in the end a 3x3 array is created. The problem is when I want an order greater than the number of vectors, say order 4 and number of vectors 3. The algorithm that I have in the else if (order == vectors) can not be applied to the case else if (order> vectors) . Any idea of being able to store an mxn array? Let's say I want to store this in an array from my inputs:

Any ideas? I'd really appreciate it, regards

HTML:

<select id="select_order">
            <option selected>Ingrese el orden del espacio vectorial</option>
            <option value="1">1</option>

            <option value="3">3</option>
            <option value="4">4</option>
            <option value="5">5</option>
            <option value="6">6</option>
            <option value="7">7</option>
            <option value="8">8</option>

                // entonces lo añadimos al arreglo principal y
