# 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]
```

Args:

• 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).

Returns:

• `Output`: The out tensor.
