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
. All
elements in x
must be complex numbers of the form \(a + bj\). The
absolute value is computed as \( \sqrt{a2 + b2}\). For example:
python
x = tf.constant([[-2.25 + 4.75j], [-3.25 + 5.75j]])
tf.abs(x) # [5.25594902, 6.60492229]
x
: A Tensor
or SparseTensor
of type float16
, float32
, float64
,
int32
, int64
, complex64
or complex128
.name
: A name for the operation (optional).A Tensor
or SparseTensor
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 x
is a SparseTensor
, returns
SparseTensor(x.indices, tf.math.abs(x.values, ...), x.dense_shape)
