What is the difference between matrix-vector multiplication and matrix-matrix multiplication?

Matrix-vector multiplication is a fundamental operation in linear algebra that combines a matrix with a vector to produce a new vector. A matrix is a rectangular array of numbers, while a vector is a collection of numbers arranged in a column or row. When you multiply a matrix by a vector, the result is a new vector whose components are linear combinations of the original vector. Think of it as a recipe: you combine ingredients (the vector) using a set of instructions (the matrix) to produce a new dish (the resulting vector).

  • Computer science: Matrix-vector multiplication is used in computer graphics, game development, and data analysis.
  • Numerical instability: Small errors in calculations can lead to significant differences in the final results.
