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.
