More About
Hyperbolic Tangent
The hyperbolic tangent of an angle x is the ratio of the hyperbolic sine and hyperbolic cosine
In terms of the traditional tangent function with a complex argument, the identity is

Version History
Introduced before R2006aR2023a: Perform calculations directly on tables and timetables
The tanh
function can calculate on all variables within a table or
timetable without indexing to access those variables. All variables must have data types
that support the calculation. For more information, see Direct Calculations on Tables and Timetables.
