bsum: Block Summation

In cgraph: Computational Graphs

Description

Divide a vector or array in consecutive fixed-sized blocks and sum the elements at each position in these blocks.

Usage

bsum(x, block_size = 1)

Arguments

x,	numerical vector or array, the object that is summed.
block_size,	numerical scalar, the size of each block. Defaults to 1.

Value

numerical vector.

Note

If x is an array and block_size is equal to the size of x's first dimension, then bsum behaves as rowSums.
