Matrix method to solve simultaneous equations
WebI have not done any benchmarking, but if I were to guess directly using matrices is probably the fastest. However, I use the lm approach if it helps explain the purpose of my code. This is clearly a vague criterion; in my case if x, y, and z are variables or factors in my analysis then I may use lm. – banbh WebThis method gives us a way to solve any matrix equation of the form 𝐴 𝑋 = 𝐵 if matrix 𝐴 is invertible. However, this method cannot be used when 𝐴 is not invertible. This could happen if 𝐴 is not a square matrix or if 𝐴 is square and d e t 𝐴 = 0. In such cases, the matrix equation has either an infinite number of solutions or no solution.
