# tensorflow::ops::Cumsum

#include <math_ops.h>

Compute the cumulative sum of the tensor x along axis.

## Summary

By default, this op performs an inclusive cumsum, which means that the first element of the input is identical to the first element of the output:

tf.cumsum([a, b, c])  # => [a, a + b, a + b + c]

By setting the exclusive kwarg to True, an exclusive cumsum is performed instead:

tf.cumsum([a, b, c], exclusive=True)  # => [0, a, a + b]

By setting the reverse kwarg to True, the cumsum is performed in the opposite direction:

tf.cumsum([a, b, c], reverse=True)  # => [a + b + c, b + c, c]

This is more efficient than using separate tf.reverse ops.

The reverse and exclusive kwargs can also be combined:

tf.cumsum([a, b, c], exclusive=True, reverse=True)  # => [b + c, c, 0]

Arguments:

• scope: A Scope object
• x: A Tensor. Must be one of the following types: float32, float64, int64, int32, uint8, uint16, int16, int8, complex64, complex128, qint8, quint8, qint32, half.
• axis: A Tensor of type int32 (default: 0). Must be in the range [-rank(x), rank(x)).

Optional attributes (see Attrs):

• exclusive: If True, perform exclusive cumsum.
• reverse: A bool (default: False).
