§1.3 Special Matrices. In this section a number of matrices that are given special names are introduced. Column Matrix: A column matrix is a matrix that has all of its entries in only one column. Row Matrix: A row matrix is a matrix that has all of its entries in a single row. Square Matrix:

Determine the inverse of the coefficient matrix. Multiply both sides of the matrix equation by the inverse matrix. In order to multiply the matrices on the right side of the equation, the inverse matrix must appear in front of the answer matrix.(the number of columns in the first matrix must equal the number of rows in the second matrix).

Substitute this value for Y into eq. (2) and solve for C: Method 2. Now solve the same problem using matrix algebra: Rewrite (1) and (2) with endogenous variables, C and Y, on left hand side. From eq. 1: Y - C = I + G. From eq. 2: -bY + C = a . Now write this in matrix notation: or A.X = B We can solve for the endogenous variables . X,
