Orthogonal Matrix Test - Eddie W. Shore - 11-04-2016 07:31 PM For the square matrix M, it is orthogonal when either of the following conditions are met: (I) M * M^T = M^T * M = I (II) M^-1 = M^T The program presented on this blog entry will use the first test. Since matrices, unfortunately, cannot be directly compared on the Casio graphing calculators, a work around with two FOR loops is implemented. HP Prime Program ORTHOG Code: EXPORT ORTHOG(m) |
