Lesson03 Dot Product And Matrix Multiplication Slides Notes
The document discusses the dot product and matrix multiplication. It defines the dot product of two vectors p and q as the sum of the element-wise products of corresponding entries. The dot product is a scalar. Matrix-vector multiplication is defined as taking the dot product of each row of the matrix with the vector to produce another vector, with the dimensions working out properly. An example calculates the matrix-vector product of a given matrix and vector.
