Solving simultaneous equations using matrix functions in Excel
MMULT Multiply two matrices together MDTERM Calculate the determinant of a specified array When solving simultaneous equations, we can use these functions to solve for the unknown values. For example, if you are faced with the following system of equations: a + 2b + 3c = 1 a –c = 0 2a + b = 1.25 Using matrix Algebra, [] [] [] To solve for the ...
