4 Application Program Interface

   

with Carter Edwards It is assumed that an application will use PLAPACK to

• Create PLAPACK vector, multivector, and matrix objects,
• Fill the entries in these PLAPACK objects,
• Perform a series of parallel linear algebra operations, and
• Query elements of the updated PLAPACK objects.

This chapter ex-pains the PLAPACK     Application Program Interface (API), which focuses on     filling and querying elements of linear algebra objects.
