Matrices

Centering matrix

In mathematics and multivariate statistics, the centering matrix is a symmetric and idempotent matrix, which when multiplied with a vector has the same effect as subtracting the mean of the components of the vector from every component of that vector. (Wikipedia).

Column space of a matrix

We have already looked at the column view of a matrix. In this video lecture I want to expand on this topic to show you that each matrix has a column space. If a matrix is part of a linear system then a linear combination of the columns creates a column space. The vector created by the

Column view of a matrix

In this tutorial I put emphasis of the column view of a matrix of coefficients. We are used to the row view when it comes to systems of linear equations, but it is the column view that is much more fascinating. The column view helps us view a system of linear equations as vectors in a sp
