poly2str

POLY2STR     Converts a polynomial array set to a string

 Usage:

   POLYSTR = POLY2STR(A, NA) where A is term coefficients vector
             and NA is the corresponding term exponents vector

   POLYSTR = POLY2STR(A, NA, BASEVAR) uses BASEVAR as base variable

   Note: Coefficient and exponent arrays are sorted according to the
         values in the exponent array in descending order prior to
         generate a polynomial string

   Examples:

        poly2str([1 -2 3], [0.5 1 0])      returns '-2s+s^0.5+3'
        poly2str([5 1 -9], [1.5 7 3], 'z') returns 'z^7-9z^3+5z^1.5'
