Baunsgaard opened a new pull request, #1807: URL: https://github.com/apache/systemds/pull/1807
This commit adds documentation for the builtins PCA and Scale. For Scale we add a NaN handling on internally calculated vectors, to allow the Scale builtin to work on inputs containing NaN, by essentially not scaling or shifting columns containing NaN. PCA now include some code examples in the documentation and minor modifications such as a new argument onlyClusters that allow us to call PCA without having to apply the calculated eigenvectors to the input matrix. This modification is done because other instances i want to compare with only calculate PCA while not applying it. Also added is some minor comments inside PCA and removal of a matrix multiplication that is never used (and so far always compiled out as dead code when executing PCA) -- This is an automated message from the Apache Git Service.
