Solve matrix equation Ax=b
11: Solve matrix equation Ax=b Solve Ax=b (and check the solution) given that A = 1 2 0 2 5 -1 4 10 -1 b = 7 8 9 Mathematica: A = { {1,2,0}, {2,5,-1}, {4,10,-1} } b = {7,8,9} x = LinearSolve[ A, b ] A . x (does equal b) Matlab: A = [ 1 2 0 ; 2 5 -1 ; 4 10 -1 ] b = [ 7 8 9 ] x = A\transpose(b) A * x (does equal b) Maple: xxx IDL: A = [ [1,2,0], [2,5,-1], [4,10,-1] ] b = [7,8,9] svd, transpose(A),..
