This functionality does not run in MATLAB.
is defined in terms of Lambert's W function as .
For x ≠ t - i π with t ≤ - 1, is a solution of the equation y + ln(y) = x. The complete solution set of this equation is
A floating-point value is computed if the argument is a floating point value. Unevaluated symbolic calls are returned for most exact arguments. For some special cases explicit symbolic representations are returned.
When called with a floating-point argument, the function is sensitive to the environment variable DIGITS which determines the numerical working precision.
Most calls with exact arguments return themselves unevaluated:
Some special arguments return explicit symbolic representations:
If the argument is a floating-point value, then a floating-point result will be returned:
An arithmetical expression, the "argument"
