Hi,

is there a in built function in Igor to solve an equation numerical?
Something like:

Variable d = solve(x, 0=x-exp(x))

and then d is the numer, which solves the equation.

Couldnt find anything...
Thank you for you help!

Also, see the following user contribution(s) for using Muller's method to find the complex roots of analytic functions:

The contributed code snippets contain no detailed help functions, but many applied math texts discuss Muller's method.
