Maple gaussian reduction multiplying rows

[deryk]

Hello, I am using maple for gaussian reduction.

I have to do it row by row for 1 part

> g:=swaprow(f,1,2);
[ 0. 3.5 3.5 3.5]

[ ]

g := [ 2 -1 -5 -7]

[ ]

[-0. 0. 0. 0.]

> h:=swaprow(g,1,2);
[ 2 -1 -5 -7]

[ ]

h := [ 0. 3.5 3.5 3.5]

[ ]

[-0. 0. 0. 0.]

> i:=addrow(h,2,1,1/3.5);
[ 2. 0. -4.000000000 -6.000000000]

[ ]

i := [ 0. 3.5 3.5 3.5]

[ ]

[-0. 0. 0. 0.]

> j:=multiplyrow(i,2,1/3.5);
j := multiplyrow(i, 2, 0.2857142857)

There is something wrong with my command but it's exactly how it shows in the help section of my maple 9 program. Does anyone know what the problem, sorry if I posted in the wrong section. thanks

Hello, it looks like your commands are correct, but you may be experiencing an issue with the precision of your calculations. Maple 9 has limited precision and may not be able to accurately perform the calculations you are trying to do. It is recommended to use a newer version of Maple or a different software that has higher precision capabilities when working with Gaussian reduction. Alternatively, you can try to adjust the precision settings in your Maple 9 program to see if that helps with the issue. Hope this helps!

Hello,

It seems like you are on the right track with using the swaprow, addrow, and multiplyrow commands in Maple for Gaussian reduction. Can you specify what exactly is going wrong with your command? Are you receiving an error message or is the output not what you expected?

One possible issue could be with the syntax of your commands. For example, in the first line of your code, you have "g:=swaprow(f,1,2);" where "f" is not defined. Make sure you are using the correct variable names and the correct number of arguments in your commands.

Another possible issue could be with the version of Maple you are using. The commands and syntax may have changed since Maple 9. It might be helpful to consult the help section or documentation for your specific version of Maple.

If you can provide more information or clarify the problem you are having, I would be happy to help troubleshoot further. Best of luck with your Gaussian reduction!
