MERGE
Matrix merge
MERGE Matrix merge
Forms a matrix from its partitions.
Format:
MERGE A11,A21,A12,A22,CP,RP/A/SYM/TYPE/FORM $
Input Data Blocks:
Aij Matrix partitions. (Real or complex).
CP Column partitioning vector.
RP Row partitioning vector.
Output Data Block:
A Merged matrix from Aij.
Parameters:
SYM Input-integer-default=-1. SYM < 0, {CP} is used for {RP}. SYM ≥ 0, {CP}
and {RP} are distinct.
TYPE Input-integer-default=0. Type of [A]. If TYPE is 0, the type of the
output matrix will be the maximum type of [A11], [A21], [A12], and
[A22].
FORM Input-integer-default=0. Form of [A]. (See Remark 3.)
Remarks:
1. MERGE is the inverse of PARTN in the sense that if [A11], [A12], [A21], [A22]
were produced by PARTN using {RP}, {CP}, FORM, SYM and TYPE from [A],
MERGE will produce [A]. The operation of MERGE is dependent upon the
partitioning vectors, {CP} and {RP}, and the symmetry flag, SYM.
