Previously, this could be done by binding the two +matrices together and calling @code{dist}, but this creates unnecessary +computation by computing the distances between a row of X and another row of +X, and likewise for Y. Pdist strictly computes distances across the two +matrices, not within the same matrix, making computations significantly faster +for certain use cases.") + (license license:gpl3+))) |
