chol.vclMatrix | R Documentation |
Compute the Choleski factorization of a real symmetric positive-definite square matrix.
## S3 method for class 'vclMatrix'
chol(x, ...)
## S3 method for class 'gpuMatrix'
chol(x, ...)

arguments to be passed to or from methods |
Default - the upper triangular factor of the Choleski decomposition, i.e. the matrix R such that R'R = x.
This an S3 generic of chol. The default continues to point to the default base function.
No pivoting is used.
The argument upper
is additionally accepted representing a boolean
which will indicate if the upper or lower (FALSE
) triangle
should be solved.
