 Author Comment/Response Rhys Ulerich 09/30/07 9:05pm Hello, I'd like to construct or somehow express an orthogonal matrix condition within Mathematica 6. I know I can use something like Q = Array[q,{3,3}] to create a symbolic 3x3 matrix, and I can express the orthogonality constraint as Q.Transpose[Q] == IdentityMatrix[3] but I'm not sure how to express it any further. What I've tried with Solve[] hasn't worked. What I ultimately want is to perform symbolic expression simplification using the assumption/fact that Q is orthogonal, e.g. something like Simplify[someExpression,orthogonalityCondition] I've found examples that give a yes/no for if a matrix is orthogonal, but no way to express the condition that one is for symbolic evaluation purposes. Any help appreciated, Rhys URL: ,
