Least Squares
In this video, I solve linear systems equations that are unsolvable (whoa!!!). More precisely, I show how to solve the systems using the least-squares method, first by doing it the Peyam way using orthogonal projections, and then by using the classical way (by multiplying by A^T). Finally, I show why the two methods are equivalent. Along the way, I also talk about the QR decomposition of a matrix. Enjoy!
