Conditions Giving Rise To Indeterminacy
In linear systems, indeterminacy occurs if and only if the number of independent equations (the rank of the augmented matrix of the system) is less than the number of unknowns and is the same as the rank of the coefficient matrix. For if there are at least as many independent equations as unknowns that will eliminate any stretches of overlap of the equations' surfaces in the geometric space of the unknowns (aside from possibly a single point); and if the rank of the augmented matrix exceeds (necessarily by one if at all) the rank of the coefficient matrix then the equations jointly contradict each other.

Famous quotes containing the words conditions, giving and/or rise:
“Statecraft is soulcraft. Just as all education is moral education because learning conditions conduct, much legislation is moral legislation because it conditions the action and the thought of the nation in broad and important spheres of life.”
—George F. Will (b. 1941)
“If the issue doesn’t matter a whole lot, just drop it. You don’t have to win every fight ... and you will not have lost any of your authority by giving in when it doesn’t matter very much.”
—Lawrence Balter (20th century)
“So in majestic cadence rise and fall
The mighty undulations of thy song,
O sightless bard, England’s Monides!
And ever and anon, high over all
Uplifted, a ninth wave superb and strong,
Floods all the soul with its melodious seas.”
—Henry Wadsworth Longfellow (1809–1882)
