POLYROOT([coeff1,coeff2,…])
This function returns the roots of the
polynomial whose coefficients are specified.
The coefficients must be input as a vector in
square brackets.
Eg. Using our earlier function of
3
() ( 2)( 3)( 1) 7 6fx x x x x x
=
−+−=−+ we
can enter the coefficients as [1,0,-7,6].
As you can see in the screen shot, the roots of 2, -3 and 1 have been
correctly found.
