dist_r: Calculate Euclidean distance between two large matrices

In sunsiyu/accr: utilities of larger-than-memory signal processing

Description

Calculate Euclidean distance between two large matrices

Usage

dist_r(m1, m2, n1 = 1, n2 = 1, len = max(0, min(nrow(m1) - n1, nrow(m2) -
  n2)), chn = min(ncol(m1), ncol(m2)), chunksize = 1e+05)

Arguments

m1,m2	matrix objects or objects of matrix shape
n1,n2	Starting index for m1 and m2
len	len to be calculated for both m1 and m2
chunksize	divide computation to chunks

Value

a numeric value, euclidean distance
