In mathematics, a matrix can be thought of as each row or column being a vector.
Hence, a space formed by row vectors or column vectors are said to be a row space or a column space.
Since these four row vectors are linearly independent, the row space is 4-dimensional.

PlanetMath: row echelon form(Site not responding. Last check: 2007-11-07)
A matrix is said to be in row echelon form if each non-zero row has more leading zeros than the previous row.
Also note that if several rows have the same number of leading zeros then the matrix is not in row echelon form unless the rows questions are composed entirely of zeros.
This is version 6 of row echelon form, born on 2002-01-26, modified 2006-01-12.
Row covers are flexible, transparent or semitransparent materials used to enclose single or multiple rows of plants so as to enhance crop growth and yield by increasing soil and air temperature and reducing wind damage (Figure 3 and Figure 4).
The floating row covers are manufactured from various fabric-like materials such as polyester or polypropylene (Figure 12), but they are non-woven material and not a fabric such as cheesecloth.
Row covers hold much potential for increasing vegetable production and net farm income by permitting growers to meet specific marketing strategies not possible without their use.
For matrices, there are three basic row operations; that is, there are three procedures that you can do with the rows of a matrix.
Row addition is similar to the "addition" method for solving systems of linear equations.
So do your work very clearly, plainly denoting the row operations you are doing; the neater you are, the more likely you'll be to get the right answer in the end, but even if you get a wrong answer, neat work is a lot easier to check.
Study: Fewer inmates on death row in '05 - USATODAY.com(Site not responding. Last check: 2007-11-07)
WASHINGTON (AP) — Fewer prison inmates were moved to death row in 2005, according to a federal study that shows one more person was executed than in the year before.
•128 inmates were moved to death row in 2005, the third consecutive year with a decline in year-long totals.
At the end of last year, 56% of death row inmates were white and 42% were fl, the Justice Department study reported.
It is done by manipulating the given matrix using the elementary row operations to put the matrix into row echelon form.
In any two successive rows that do not consist entirely of zeros, the leading 1 in the lower row occurs farther to the right that the leading 1 in the higher row.
If a zero is placed in the main diagonal of the row being operated on, when you divide that row by the diagonal number the division by zero error will occur.

Other then that be safe, have a happy break away from ROW and don't be afraid to message me or to check the boards and the site in the mean time.
Rumors have it that a rebellion occured amongst Staff and Roster and resulted in the termination of 80% of the Roster.
Champions who plan to stay with ROW when the come back tour starts will retain their gold but those who have been fired or have quit will lose their gold and tournaments will be held to win those titles.
Front Row makes it possible to showcase your digital work the way it was meant to be seen: on a brilliant 15- or 17-inch display, at the touch of the Apple Remote.
After turning on and plugging in your external display or projector, simply hit the F7 key to switch between dual display and presentation notes.
MacBook Pro with Front Row works with a host of projectors, thanks to DVI, VGA, S-video, and composite connectivity.
