Matrices

Things you need to know:

• A^t means to switch the rows and columns in the matrix.
• When you are adding matrices, they must be the same dimensions (rows x columns).
• When you are adding matrices, you add the corresponding entries.
• When you are doing multiplication, you multiply every entry by the number.

Example: 1

• What are the dimensions of the matrix? 2x3 (2 rows x 3 columns)
• Find M^t.
• Find 2M.
