Matrix CalculatorA bit primitive, but what do you think? Works? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20100513 12:34:09
Re: Matrix CalculatorHi MathsisFun; for this one I am getting. The det(A) is 0 not 3.199999999 Also because the determinant is 0 this matrix is singular, no inverse. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20100514 02:56:28
Re: Matrix CalculatorNice page! Why did the vector cross the road? It wanted to be normal. #4 20100514 03:14:47

Re: Matrix CalculatorThanks for the feedback! It may take me a while to work on it. First up: the det(A) bug. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #6 20100514 14:58:19
Re: Matrix CalculatorOK, got most of your requests done I think: "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #7 20100514 15:33:55

Re: Matrix CalculatorThat's a mean matrix. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #9 20100514 20:38:07
Re: Matrix CalculatorFunny thing is I have never seen them used in any application other than for proving how hard they are to invert. In mathematics, you don't understand things.

Re: Matrix CalculatorThe only complaint I can think of probably doesn't apply to many people here, but if both matrices are 10x10, then B gets cut off. Linux FTW
