- The internal structure of the
MATRIX
data type has been changed from Vector<float[]> to float[][] with internal methods for dynamic resizing. - A new
M_OPS
FB type with expanded functionality replaces the formerM_COLS
FB type. - A new data type
M_OP
is used to enumerate the functionality provided by the newM_OPS
FB type. - Row and column indices and lengths are now restricted to the values
{0..255}
of theUSINT
data type to correspond to the single-octet elements used for this purpose in the ASN.1 encoding. - Matrix inversion is now performed using the Product Form of the Inverse (PFI). The PFI column pivot operation is also directly supported by the
M_OPS
FB type, which makes it potentially useful in the solution of linear programming optimization problems. - The
OUT_MATRIX
FB type is now capable of resizing and redisplaying itself when aREQ
event is received, so theIVAL, ROWS
andCOLS
inputs have been eliminated from this FB type, and no table is displayed initially until the firstREQ
event is received. - The
TEST_MCOLS
system configuration has been updated toM_OPS_DEMO
to demonstrate all the operations possible on the new M_OPS FB type. - The
TEST_MATRIX
system configuration has been renamed to the more descriptiveMATRIX_DEMO
.

PUBLISH/SUBSCRIBE in Applets
PUBLISH and SUBSCRIBE have been upgraded to switch automatically to local multicast channels when their environment does not support UDP communication, e.g., in Applets. See the PUBLISH_0 documentation in the net folder and the CODEC_TEST and CODEC_TEST2 examples in the ita folder of the FB Navigator.

PUBLISH/SUBSCRIBE Update
The implementation of PUBLISH and SUBSCRIBE has been updated to ensure that all data transfer can occur within a single Ethernet packet using UDP over IPv4. For details, see www.holobloc.com/doc/fb/rt/net/pubsub.htm and http://www.holobloc.com/doc/ita/s3.htm#3.5.
