Detailed Description

Returns the upper triangle of a SparseMatrixRange.

Examples:

   [1 2 z]      [1 2 z]

triu ( [4 5 6] ) -> [z 5 6] [7 8 9] [z z 9]

triu ( [1 2 3] ) -> [1 2 3] [4 5 6] [z 5 6]

[1 2] [1 2] triu ( [3 4] ) -> [z 4] [5 6]

Here z indicates a structural zero. Note that triu() crops excess rows.
