Is there a word for the degree of how much a system of equations is underdetermined?
Does the word
exist? I also found
but it seems to be a philosophical term.
Background: The values of a system of (say) 100 variables is in general determined by at least 100 equations. If you just have 99 equations the system is slightly underdetermined. If you just have a few equations its highly underdetermined.
In other words: Is there a word for the ratio (number of equations)/(number of variables)?
