Incorrect initialization of LDWORK in sb03md #165
Description
According to the SLICOT documentation for LDWORK of SB03MD:
LDWORK INTEGER
The length of the array DWORK. LDWORK >= 1, and
If JOB = 'X' then
If FACT = 'F', LDWORK >= N*N, for DICO = 'C';
LDWORK >= MAX(N*N, 2*N), for DICO = 'D';
If FACT = 'N', LDWORK >= MAX(N*N, 3*N).
If JOB = 'S' or JOB = 'B' then
If FACT = 'F', LDWORK >= 2*N*N, for DICO = 'C';
LDWORK >= 2*N*N + 2*N, for DICO = 'D'.
If FACT = 'N', LDWORK >= MAX(2*N*N, 3*N), DICO = 'C';
LDWORK >= 2*N*N + 2*N, for DICO = 'D'.
For optimum performance LDWORK should be larger.
[...]
However, LDWORK is set to
Lines 790 to 791 in 063fed3
disregarding the values of
JOB, FACT and DICO.
Which gives me
slycot.exceptions.SlycotParameterError: The following argument had an illegal value: ldwork
for JOB='B', FACT='N' and DICO='D'
I know that I can set ldwork manually, but IMHO that sort of thing is precisely what the wrapper should do for me :^)
