TANH Function

Returns the hyperbolic tangent of the input variable.

result = TANH(x)

x The angle, in radians, that is evaluated.

result The hyperbolic tangent of x.

None.

TANH is defined by:


If x is of double-precision floating-point or of complex data type, TANH yields a result of the same type. All other data types yield a single-precision floating-point result.

If x is an array, the result of TANH has the same dimensions, with each element containing the hyperbolic tangent of the corresponding element of x.

x = [0.3, 0.5, 0.7, 0.9]
