The transpose simply interchanges the rows with the columns. Matrix Algebra Matrices are basically tables. They are ways of storing numbers and other things.
Typical matrix has rows and columns.
Actually called a 2-way matrix because it has two dimensions. Of course, you might collect the same data on the same people at 5 points in time. Notice that the rows and columns point to different class of entities. Rows are people, and columns are properties. Each different class of entities in a matrix is known as a mode.
