Matrix characteristics

Identifier: IMPCOL_D

Type: Unsymmetric with many zeros on the diagonal. Some of the entires actually have the value zero. This happens when a procedure is used in which all outputs are incorrectly assumed to be a function of all inputs.

Order : 425

# of entries: 1339

Performance: These matrices can be significantly reduced by block triangularization methods.
