For example, for matrix A, B, I know that when I use LinearSolve [A,B] that means it will solve for x which fulfill Ax=B. However, what if xA=B case. I was trying to … WebSolvability conditions on b We again use the example: ⎡ ⎤ 1 2 2 2 A = ⎣ 2 4 6 8 ⎦ . 3 6 8 10 The third row of A is the sum of its first and second rows, so we know that if Ax = b the third component of b equals the sum of its first and second components. If b does not satisfy b3 = b1 + b2 the system has no solution. fitzgerald weather forecast
