 Author Comment/Response Peter Pein 10/06/07 07:47am In Response To 'Re: Re: solve symbolic matrix equation'---------Hi Nikola, (wrong forum or wrong CAS? ;-)) be sure to multiply the inverse of c "from the correct side" (matrix multiplication is not commutative!). For example (Mathematica (not Maple) 5.2): SeedRandom[20071006]; {a,b,c}=Array[Random[]&,{3,3,3}]; d1=Inverse[c].(a-b) (* correct *); d2=(a-b).Inverse[c] (* faulty *); a == b+c.#& /@ {d1,d2} --> {True,False} Regards, Peter URL: ,
