tf.math.is_non_decreasing(
    x, name=None
)

Elements of x are compared in row-major order. The tensor [x[0],...] is non-decreasing if for every adjacent pair we have x[i] <= x[i+1]. If x has less than two elements, it is trivially non-decreasing.

See also: is_strictly_increasing

x1 = tf.constant([1.0, 1.0, 3.0])
tf.math.is_non_decreasing(x1)
<tf.Tensor: shape=(), dtype=bool, numpy=True>
x2 = tf.constant([3.0, 1.0, 2.0])
tf.math.is_non_decreasing(x2)
<tf.Tensor: shape=(), dtype=bool, numpy=False>

Args
`x`	Numeric `Tensor`.
`name`	A name for this operation (optional). Defaults to "is_non_decreasing"

Returns
Boolean `Tensor`, equal to `True` iff `x` is non-decreasing.

Raises
`TypeError`	if `x` is not a numeric tensor.
