| 240 | Return minimum of an array or minimum along an axis, ignoring any NaNs. |
| 241 | When all-NaN slices are encountered a ``RuntimeWarning`` is raised and |
| 242 | Nan is returned for that slice. |
| 243 | |
| 244 | Parameters |
| 245 | ---------- |
| 246 | a : array_like |
| 247 | Array containing numbers whose minimum is desired. If `a` is not an |
| 248 | array, a conversion is attempted. |
| 249 | axis : {int, tuple of int, None}, optional |
| 250 | Axis or axes along which the minimum is computed. The default is to compute |
| 251 | the minimum of the flattened array. |
| 252 | out : ndarray, optional |
| 253 | Alternate output array in which to place the result. The default |
| 254 | is ``None``; if provided, it must have the same shape as the |
| 255 | expected output, but the type will be cast if necessary. See |
| 256 | :ref:`ufuncs-output-type` for more details. |
| 257 | |
| 258 | .. versionadded:: 1.8.0 |
| 259 | keepdims : bool, optional |
| 260 | If this is set to True, the axes which are reduced are left |
| 261 | in the result as dimensions with size one. With this option, |
| 262 | the result will broadcast correctly against the original `a`. |
| 263 | |
| 264 | If the value is anything but the default, then |
| 265 | `keepdims` will be passed through to the `min` method |
| 266 | of sub-classes of `ndarray`. If the sub-classes methods |
| 267 | does not implement `keepdims` any exceptions will be raised. |
| 268 | |
| 269 | .. versionadded:: 1.8.0 |
| 270 | initial : scalar, optional |
| 271 | The maximum value of an output element. Must be present to allow |
| 272 | computation on empty slice. See `~numpy.ufunc.reduce` for details. |
| 273 | |
| 274 | .. versionadded:: 1.22.0 |
| 275 | where : array_like of bool, optional |
| 276 | Elements to compare for the minimum. See `~numpy.ufunc.reduce` |
| 277 | for details. |
| 278 | |
| 279 | .. versionadded:: 1.22.0 |
| 280 | |
| 281 | Returns |
| 282 | ------- |
| 283 | nanmin : ndarray |
| 284 | An array with the same shape as `a`, with the specified axis |
| 285 | removed. If `a` is a 0-d array, or if axis is None, an ndarray |
| 286 | scalar is returned. The same dtype as `a` is returned. |
