RE: [NMusers] permissible band matrix

Hi Sam,

It might have something to do with the fact that the second example can be
written with two $BLOCK(2) statements and the first example can't.

Cheers... Brian

Subject: [NMusers] permissible band matrix

Dear NONMEM users:

Can someone please help me to solve this problem with a band matrix?

$OMEGA BLOCK(4)
 0.09 ;BSV_V1C
 0.07 0.09 ;BSV_CLC
 0 0.07 0.09 ;BSV_CLN
 0 0 0.07 0.09 ;BSV_V1N
Why this one above is getting an error in NONMEM?

$OMEGA BLOCK(4)
 0.09 ;BSV_V1C
 0.07 0.09 ;BSV_CLC
 0 0 0.09 ;BSV_CLN
 0 0 0.07 0.09 ;BSV_V1N
This one above is fine, but I need to run a simulation in which there
are some correlation between CLC and CLN.

There were some very helpful discussion on band matrix few years ago.
But I still couldn't figure out why this band matrix not permissible.
