crossprod: Cross-product of large sparse matrices

In proxyC: Computes Proximity in Large Sparse Matrices

Cross-product of large sparse matrices

Description

Compute the (transposed) cross-product of large sparse matrices using the same infrastructure as simil() and dist().

Usage

crossprod(x, y = NULL, min_prod = NULL, digits = 14)

tcrossprod(x, y = NULL, min_prod = NULL, digits = 14)

Arguments

x	a base::matrix or Matrix::Matrix object. Dense matrices are covered to the Matrix::CsparseMatrix internally.
y	if a base::matrix or Matrix::Matrix object is provided, proximity between documents or features in x and y is computed.
min_prod	the minimum product to be recorded.
digits	determines rounding of small values towards zero. Use primarily to correct floating point errors. Rounding is performed in C++ in a similar way as base::zapsmall.
