ng storage for internal container pointers and sizes. The
total memory usage is roughly <span class="math inline">\(12 K + M\)</span> bytes plus a small constant
overhead, which is often considerably fewer bytes than the <span class="math inline">\(M \times N\)</span> required to store a dense matrix. Even more importantly, zero
values do not introduce derivatives under multiplication or addition,
so many storage and evaluation steps are saved when sparse matrices
are multiplied.</p>
