Mojo module

reduction

Implements SIMD reductions.

You can import these APIs from the algorithm package. For example:

from std.algorithm import map_reduce

Functions

cumsum: Computes the cumulative sum of all elements in a buffer. dst[i] = src[i] + src[i-1] + ... + src[0].
map_reduce: Stores the result of calling input_gen_fn in dst and simultaneously reduce the result using a custom reduction function.
max: Computes the max across the input and output shape.
mean: Computes the mean across the input and output shape.
min: Computes the min across the input and output shape.
product: Computes the product across the input and output shape. This performs the product computation on the domain specified by input_shape, loading the inputs using the input_fn. The results are stored using the output_fn.
reduce: Computes a custom reduction of buffer elements.
reduce_boolean: Computes a bool reduction of buffer elements. The reduction will early exit if the continue_fn returns False.
sum: Computes the sum across the input and output shape.
variance: Given a mean, computes the variance of elements in a buffer.
