Format Distance Matrix (Matlab Style)
Description
Format or generate a distance matrix.
Usage
squareform(x)
Arguments
x
numeric vector or matrix.
Details
If x is a vector as created by the dist function, it converts
it into a fulll square, symmetric matrix.
And if x is a distance matrix, i.e. square, symmetric amd with zero
diagonal elements, it returns the flattened lower triangular submatrix.
Value
Returns a matrix if x is a vector,
and a vextor if x is a matrix.

Examples
x <- 1:6
y <- squareform(x)
# 0 1 2 3
# 1 0 4 5
# 2 4 0 6
# 3 5 6 0
all(squareform(y) == x)
# TRUE
