Function Description

  • Operator function: computes the Dawson integral F(x) = exp(-x^2) * integral_0^x exp(t^2) dt.

  • Computation formula:

F(x)=e−x2∫0xet2dtF(x) = e^{-x^{2}} \int_{0}^{x} e^{t^{2}} \mathrm{d}t

Parameter Description

Parameter Name Input/Output/Attribute Description Data Type Data Format
x Input Input parameter for the Dawson integral computation, which is x in the formula. BFLOAT16, FLOAT16, FLOAT ND
y Output Output parameter for the Dawson integral computation, which is F(x) in the formula. BFLOAT16, FLOAT16, FLOAT ND

Constraint Description

  • The DOUBLE (FP64) data type is not supported.
