Data Type

Integer

Default Value

2

Description

This parameter controls the amount of printed output produced by calls to the matrix and vector assembly routines RSDA, RNDA, CHDA, CSDA, CNDA, RSDAF, RNDAF, CHDAF, CSDAF, CNDAF, RSDANN, RNDANN, CHDANN, CSDANN, CNDANN and RSDAV, CSDAV The print code summary table lists the values of IPRA and the output produced.

The following is a detailed description of each option. The value of IPRA you specify is obtained by adding together the numeric value of each option you select. Because these numeric values are a power of 2, they have the effect of setting bits in IPRA.

  • 0, No output from matrix assembly is printed.
  • +1, Start and stop timing is printed.
    The following is an example: 
     START OF FMS MATRIX ASSEMBLY
 END   OF FMS MATRIX ASSEMBLY.
 TIME(SEC): CPU   =       0.314,        WALL=       0.340
  • +2, Timing information is printed for the assembly of each matrix segment.
    The following is an example: 
     F M S     M A T R I X     A S S E M B L Y

  • +4, Right-hand side vectors {RHS} are printed after assembly.
  • +8, The element matrices [Si] and element vectors {Vi} are printed before assembly.
  • +64, The matrix diagonals [D] are printed after assembly.
  • +256, The lower triangle matrix [AL] and upper triangle matrix [AU] (nonsymmetric) are printed after assembly.
  • +2048, The number of terms within the matrix profile are counted.
    This value becomes available as the FMS parameter ATERMS.
