Example Question #808 : Linear Algebra
Let be a matrix and
be a vector defined by:
Find the product .
The product does not exist because the dimensions do not match.
First we check the dimensions. The matrix has 3 columns and the vector
has three rows. The dimensions match and the product exists.
Now we take the dot product of rows in the matrix and the vector .
