Metzler matrix

Metzler matrices are special types of matrices that have only positive numbers. Metzler matrices are usually used to help solve equations. They are helpful because all of the numbers in the matrix are positive which makes it easier to solve an equation. For example, if you wanted to figure out how many cookies you need, you could write down the number of people who need cookies and the number of cookies each person needs in a Metzler matrix. Then, you would add up the numbers in the matrix and that would give you the total number of cookies you need.
