Computes the absolute value of a tensor.
tf.math.abs( x, name=None )
Given a tensor of integer or floating-point values, this operation returns a tensor of the same type, where each element contains the absolute value of the corresponding element in the input.
Given a tensor x
of complex numbers, this operation returns a tensor of type float32
or float64
that is the absolute value of each element in x
. For a complex number \(a + bj\), its absolute value is computed as \(\sqrt{a^2
x = tf.constant([[-2.25 + 4.75j], [-3.25 + 5.75j]]) tf.abs(x) <tf.Tensor: shape=(2, 1), dtype=float64, numpy= array([[5.25594901], [6.60492241]])>
Args | |
---|---|
x | A Tensor or SparseTensor of type float16 , float32 , float64 , int32 , int64 , complex64 or complex128 . |
name | A name for the operation (optional). |
Returns | |
---|---|
A Tensor or SparseTensor of the same size, type and sparsity as x , with absolute values. Note, for complex64 or complex128 input, the returned Tensor will be of type float32 or float64 , respectively. If |
