We have the following matrix :

How can I found a triangle matrix similar to the initial matrix.

I was pleased if someone show me the step by step solution because I have 2 more matrices to do exactly the same procedure.

Thanks in Advance

Here's my idea: Find the eigenvalues of the matrix A and put them into a diagonal matrix.

Since a diagonal matrix is both upper and lower triangular, it's triangular.

Is there anything wrong with this idea? - March 22nd 2009, 11:55 AMypatia
