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.

x1 = tf.constant([1.0, 1.0, 3.0])

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.
