I have tried to declare:
octave_user_function f = @(p,x) 1-exp(p*x);
but I've got 1) error: stray address@hidden in program and 2) error: ‘p, x’ was not
declared in this scope
Why the octave interpreter doesn't understand @ sign?
How to properly declare an anonymous function or how to write a function
that will return an object octave_user_function?
Should I provide any additional headers (include <???>) when declaring
anonymous functions?
Maybe there is another way to transfer user function (@(p,x) 1-exp(p*x)) as
an argument for octave::feval?
It would be really great if I could use this function. My ideas for a
solution are exhausted. I need your help.

does this help
>>str1='@(p,x) 1-exp(p*x);'
str1 = @(p,x) 1-exp(p*x);
>>fh=str2func(str1)
fh = @(p, x) 1 - exp (p * x)
>> fh(2,4)
ans = -2980.0
start with a string use octave to convert it to a function handle and the use feval from c++
