Function Description

  • Operator function: computes the Hurwitz zeta function, that is, ζ(x, q) = Σ(n=0 to ∞) 1/(q+n)^x.

  • Computation formula:

z=ζ(x,q)=∑n=0∞1(q+n)xz = \zeta(x, q) = \sum_{n=0}^{\infty} \frac{1}{(q+n)^x}

Parameter Description

Parameter Name Input/Output/Attribute Description Data Type Data Format
x Input Input tensor, which is the exponent parameter of the Hurwitz zeta function. FLOAT, DOUBLE ND
q Input Input tensor, which is the shift parameter of the Hurwitz zeta function. It must have the same data type as x. FLOAT, DOUBLE ND
z Output Output tensor, which is the computation result of the Hurwitz zeta function and has the same type and shape as x. FLOAT, DOUBLE ND

Constraint Description

  • The inputs x and q must have the same data type.
  • The inputs x and q must have the same data size (broadcast is not supported).

Invocation Description

Invocation Method Sample Code Description
Graph-mode invocation test_geir_zeta Invokes the Zeta operator through the operator IR API.
