[jira] [Reopened] (MATH-862) AbstractRealMatrix should check that all supplied double[][] arrays are rectangular

     [ https://issues.apache.org/jira/browse/MATH-862?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Thomas Neidhart reopened MATH-862:
----------------------------------


My fix was wrong for copySubMatrix, as the javadoc states that the provided array does not have to be strictly the size of the submatrix to be copied. The check should take this into account and only verify that there is enough place for the copy operation.

> Many methods in RealMatrix take as an argument a {{double[][]}} as the representation of a matrix. As such, the array should be rectangular. Checks should be provided, as requested in the Javadoc of e.g. {{void setSubMatrix(double[][], int, int)}}.
