• Dimensions of a matrix: numbers of rows by numbers of columns. The Matrix A is a 2x2 matrix, b is a 1x3 matrix. • A matrix with only 1 column or only 1 row is called a vector. • If a matrix has an equal numbers of rows and columns, it is called a square matrix. Matrix A, above, is a square matrix.
