BASIC matrix methods, including applications in approximation and data fitting Book

This is a unique & really lovely collection of photos. Even though some of the original daguerreotypes are small, almost all the photos are uniformly-sized into full-page photos here; that, coupled with the high-quality print job, lets you see & appreciate the beauty & details of these early photos. There are some details available about some of the portrait subjects, but usually very little. It's too bad that the details of people's lives have been lost to the sands of history. A beautiful collection, lovingly presented.
