# xarray.Dataset.broadcast_equals

#### Dataset.broadcast_equals(other)[[source]](https://github.com/pydata/xarray/blob/main/xarray/core/dataset.py#L1640-L1705)

Two Datasets are broadcast equal if they are equal after
broadcasting all variables against each other.

For example, variables that are scalar in one dataset but non-scalar in
the other dataset can still be broadcast equal if the the non-scalar
variable is a constant.

# 2D array with shape (1, 3)

```pycon
>>> data = np.array([[1, 2, 3]])
>>> a = xr.Dataset(
...     {"variable_name": (("space", "time"), data)},
...     coords={"space": [0], "time": [0, 1, 2]},
... )
>>> a
<xarray.Dataset> Size: 56B
Dimensions:        (space: 1, time: 3)
Coordinates:
  * space          (space) int64 8B 0
  * time           (time) int64 24B 0 1 2
Data variables:
    variable_name  (space, time) int64 24B 1 2 3
```

# 2D array with shape (3, 1)

```pycon
>>> data = np.array([[1], [2], [3]])
>>> b = xr.Dataset(
...     {"variable_name": (("time", "space"), data)},
...     coords={"time": [0, 1, 2], "space": [0]},
... )
>>> b
<xarray.Dataset> Size: 56B
Dimensions:        (time: 3, space: 1)
Coordinates:
  * time           (time) int64 24B 0 1 2
  * space          (space) int64 8B 0
Data variables:
    variable_name  (time, space) int64 24B 1 2 3
```

.equals returns True if two Datasets have the same values, dimensions, and coordinates. .broadcast_equals returns True if the
results of broadcasting two Datasets against each other have the same values, dimensions, and coordinates.

```pycon
>>> a.equals(b)
False
```

```pycon
>>> a.broadcast_equals(b)
True
```

```pycon
>>> a2, b2 = xr.broadcast(a, b)
>>> a2.equals(b2)
True
```
