HermiteH

 HermiteH[n, x]gives the Hermite polynomial .
• Mathematical function, suitable for both symbolic and numerical manipulation.
• Explicit polynomials are given for non-negative integers n.
• The Hermite polynomials satisfy the differential equation .
• They are orthogonal polynomials with weight function in the interval .
• For certain special arguments, HermiteH automatically evaluates to exact values.
• HermiteH can be evaluated to arbitrary numerical precision.
• HermiteH automatically threads over lists.
• HermiteH[n, x] is an entire function of x with no branch cut discontinuities.
