HERMPOLY is the jCommon module of jLab.

 HERMPOLY   Hermite polynomial of degree n.
    H = HERMPOLY(N) returns the chebfun corresponding to the 'physicist'-type
    Hermite polynomials H_N(x) on [-inf,inf] (orthogonal with respect to the
    weight exp(-x.^2)). N may be a vector of positive integers.
 
    H = HERMPOLY(N, 'PROB') normalises instead by the probablist's definition
    (with weight exp(-x.^2/2)), which gives rise to monic polynomials.
 
    Note, this is currently just a toy to play with the construction of Hermite
    polynomials using a combination of Chebfun's barycentric, mapping, and
    'blowup' technologies.
