when i call Routh_H([1,1,1,1,1]),
it return

Error using cell
Conversion to cell from sym is not possible.

Error in Routh_H (line 96)
Table = cell(limit(Table,e,0,'right'));

please check!

How many of these do we need, especially since this is an academic exercise? There must be at least a half dozen of these on the FEX.
all(real(roots(p)))<0 returns true if the roots of the polynomial having coefficients in row vector p are in the left half plane.
