tanh
Syntax
tanh(X)
Details
The hyperbolic tangent function.
Note:
DolphinDB's
tanh function accepts only one
argument and supports calculations on scalars, vectors, and matrices. By contrast,
NumPy's tanh function is a generalized ufunc that supports
N-dimensional arrays of any shape. You can control the output and apply conditional
computation through parameters such as out and where.Parameters
X is a scalar/vector/matrix.
Returns
DOUBLE type with the same data form as X.
Examples
tanh(0 1 2);
// output: [0,0.761594,0.964028]
