# FindPolynomialZeroes

Non-exposed, non-supported function

## FindPolynomialZeroes(C, I, J)

Finds all real-number factors of a polynomial.

The polynomial is specified by its coefficients, «C», in the first parameter, indexed by «I». The first element along «I» is the constant, the second parameter is the linear coefficient, the third the quadratic coefficient, etc., so that the full polynomial for a value X is

`Sum(C*X^(@I - 1), I)`

There are at most n - 1 solutions. The real-valued solutions (or zeroes) are returned in an array also indexed by «I». The last elements along «I» are filled with NaN when the remaining solutions are complex (since only the real-valued solutions are found and returned). The final slot will always be NaN since there are at most n - 1 solutions. Alternatively, you can supply an optional third parameter, «J», with one element less than «I», which will be used to index the result.

The highest order coefficient should always be non-zero.
