# Maple gaussian reduction multiplying rows

Hello, Im 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.]

[ 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
