This functionality does not run in MATLAB.
dawson(x) represents Dawson's integral, which is defined as .
dawson(x) returns special values for x = 0 and . For all other symbolic values of x, unevaluated function calls are returned. Cf. Example 1.
When called with floating-point arguments, this function is sensitive to the environment variable DIGITS which determines the numerical working precision.
For the following arguments, special values are returned:
dawson(0), dawson(infinity), dawson(-infinity)
For other symbolic arguments, a symbolic call is returned:
Floating point values are returned for floating-point arguments:
dawson(0.0), dawson(1.0), dawson(-3.4 + 0.2*I)
diff(dawson(x^2), x), float(dawson(7))
limit(x*dawson(x), x = infinity)
series(dawson(x), x = infinity, 4)
