overridevirtual

Get the data of the specified row.

If the matrix is a block matrix (i.e., the block size is greater than one), the pattern defines the global ids of the block columns of the row, where a block column is defined as a group of block-size matrix columns.

If the matrix is a block matrix (i.e., the block size is greater than one), the values contain of all the elements of a block row, where a block column is defined as a group of block-size matrix columns. The values are returned as a row-oriented logically two-dimensional array of values.

Parameters

rowIndex	is the index of the row in the assembler
pattern	on output will contain the pattern of the specified (block) row
values	on output will contain the values of the specified (block) row. If the block size is greater than one, values will be stored in a logically two-dimensional array that uses a col-major order
