%Create the coefficient matrix C and column matrix of constants d. C = [4 1; 2 -3] d = [5; 13] %Note: Cramer's Rule only applies to systems of linear equations with invertible square %coefficient matrices. %Initialize the matrices C1 and C2 to equal C. C1 = C C2 = C %Replace column 1 in C1 with the column vector of constants d. C1(:,1)=d %Replace column 2 in C2 with the column vector of constants d. C2(:,2)=d %The solution can now be found using ratios of determinants. x = det(C1)/det(C) y = det(C2)/det(C)
