collapse#
- class saiunit.lax.collapse(x, start_dimension, stop_dimension=None, unit_to_scale=None, **kwargs)#
Collapses dimensions of an array into a single dimension.
For example, if
operandis an array with shape[2, 3, 4],collapse(operand, 0, 2).shape == [6, 4]. The elements of the collapsed dimension are laid out major-to-minor, i.e., with the lowest-numbered dimension as the slowest varying dimension.- Parameters:
x (
Union[saiunit.Quantity,Array,ndarray,number,bool]) – an input array.start_dimension (
int) – the start of the dimensions to collapse (inclusive).stop_dimension (
Optional[int]) – the end of the dimensions to collapse (exclusive). Pass None to collapse all the dimensions after start.unit_to_scale (
Optional[saiunit.Unit]) – the unit to scale the input to. If None, the input should be dimensionless.
- Return type:
Array- Returns:
An array where dimensions
[start_dimension, stop_dimension)have been collapsed (raveled) into a single dimension.
