assemblepolystring(​polyCoeffs,varName,​fncName,varargin)

Create a polynomial equation (text string) from polynomial coefficients (vector)

Function creates a text string, being the equation of a polynomial, with coefficients listed in order of decreasing power in the vector 'polyCoeffs' (Vector, as returned from MATLAB function 'polyfit' and used by 'polyval').
It allows the user to select names of the free and dependent variables. It is also possible to append a unit string (i.e. "m") to the very end of the string.
