Table diagonalization

Diagonalization is the process of re-ordering the rows and columns of tables and charts so that the data forms an approximately diagonal line. This makes it easier for people to see patterns in the data. Diagonalization typically involves either raw data, percentages, means or residuals. Generally once tables are diagonalized one of two patterns appears: hierarchy or segmentation (Wikipedia).

How the Diagonalization Process Works

Description: Our goal is to fix a diagonal matrix that is similar to our given matrix. Why? Diagonal matrices are simple, and if two matrices are similar then they share many properties like the same eigenvalues. So similar to a diagonal matrix will allows us to quickly compute many proper

Simultaneous Diagonalization

In this video, I define the notion of simultaneous diagonalization and show that two matrices are simultaneously diagonalizable if and only if they commute (that is AB = BA). This is a wonderful exercise using invariant subspaces and diagonalization. Enjoy! Check out my Diagonalization pl

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

Diagonalization

Now that we know about eigenvalues and eigenvectors, we are ready to learn about diagonalization. This involves writing a matrix as a product of other matrices, one of which is a diagonal matrix, with values only along the main diagonal. This has many applications in computation, so let's

Is the Sieve of Eratosthenese past its prime?

The Sieve of Eratosthenes is an amazing tool for teaching people about prime numbers and composite numbers but it's not without its limitations. I've tried to answer the question, 'Is there a better way of representing a sieve like this?' 0:00 Sieve of Eratosthenes In the first part of t
