The Soboleva modified hyperbolic tangent function, often represented as \\( \\tanh_s(x) \\), is a mathematical function that is a modification of the standard hyperbolic tangent function. In various domains, including physics and engineering, such modified functions are introduced to better handle specific properties such as asymptotic behavior, smoothness, or to meet certain boundary conditions.
