MPYAD A , B , / D $
Instructions
According to the MPYAD module description, if C is unspecified, then only the matrix
multiplication of A and B is performed. Also, by default, T=0 and therefore A is not
transposed. SIGNAB and SIGNC parameters are defaulted to 1 resulting in:
[D] = [A][B]
However, if no default is defined in the MPL, then a constant or variable parameter
must be specified for the first parameter. For example,
-- NO DEFAULT --
on the PARAML module indicates there is no default value for the first parameter.
The first comma after the module name can be omitted as long as the first input data
block name is specified. For example, the ELTPRT module has the following format:
ELTPRT ECT,GPECT,BGPDT,UNUSED4,EST,CSTM,MPT,DIT,CASECC/
VELEM/PROUT/S,N,ERROR $
To obtain a printout of the elements connected to each grid point, only GPECT and
BGPDTS need to be specified; however, a comma must also be specified after the
module name:
In addition, trailing commas can be left unspecified:
Parameters can be specified on a module as:
input only
input and output
output only
ELTPRT , ,GPECT,BGPDTS,,,,,,/ $
ELTPRT , ,GPECT,BGPDTS,,,,,,/ $
Each module has its own rules for parameter specification, as described in “Detailed
Descriptions of DMAP Modules and Statements” on page 766. If a parameter is
specified as input, then either a constant or variable can be specified. Note that
character strings or variables specified for parameters are limited to eight characters
in length.
For example, the first parameter of the ADD module specifies a scalar multiplier of
1+2i on the first input matrix:
ADD A , B / C / (1.,2.) $
