WebWe used vector norms to measure the length of a vector, and we will develop matrix norms to measure the size of a matrix. The size of a matrix is used in determining whether the solution, x, of a linear system Ax = b can be trusted, and determining the convergence rate of a vector sequence, among other things. We define a matrix norm in the same way we … WebFrom the video, the equation of a plane given the normal vector n = [A,B,C] and a point p1 is n . p = n . p1, where p is the position vector [x,y,z].
