ulab.numerical – Numerical and Statistical functions¶
Most of these functions take an “axis” argument, which indicates whether to operate over the flattened array (None), rows (0), or columns (1).
-
ulab.numerical.argmax(array: _ArrayLike, *, axis: Optional[int] = None) → int¶ Return the index of the maximum element of the 1D array
-
ulab.numerical.argmin(array: _ArrayLike, *, axis: Optional[int] = None) → int¶ Return the index of the minimum element of the 1D array
-
ulab.numerical.argsort(array: ulab.array, *, axis: Optional[int] = None) → ulab.array¶ Returns an array which gives indices into the input array from least to greatest.
-
ulab.numerical.diff(array: ulab.array, *, axis: int = 1) → ulab.array¶ Return the numerical derivative of successive elements of the array, as an array. axis=None is not supported.
-
ulab.numerical.flip(array: ulab.array, *, axis: Optional[int] = None) → ulab.array¶ Returns a new array that reverses the order of the elements along the given axis, or along all axes if axis is None.
-
ulab.numerical.max(array: _ArrayLike, *, axis: Optional[int] = None) → float¶ Return the maximum element of the 1D array
-
ulab.numerical.mean(array: _ArrayLike, *, axis: Optional[int] = None) → float¶ Return the mean element of the 1D array, as a number if axis is None, otherwise as an array.
-
ulab.numerical.min(array: _ArrayLike, *, axis: Optional[int] = None) → float¶ Return the minimum element of the 1D array
-
ulab.numerical.roll(array: ulab.array, distance: int, *, axis: Optional[int] = None) → None¶ Shift the content of a vector by the positions given as the second argument. If the
axiskeyword is supplied, the shift is applied to the given axis. The array is modified in place.
-
ulab.numerical.sort(array: ulab.array, *, axis: Optional[int] = 0) → ulab.array¶ Sort the array along the given axis, or along all axes if axis is None. The array is modified in place.
-
ulab.numerical.std(array: _ArrayLike, *, axis: Optional[int] = None) → float¶ Return the standard deviation of the array, as a number if axis is None, otherwise as an array.
-
ulab.numerical.sum(array: _ArrayLike, *, axis: Optional[int] = None) → Union[float, int, ulab.array]¶ Return the sum of the array, as a number if axis is None, otherwise as an array.
