# Line 1936 | Line 1936 | by Rob Guglielmetti.
1936   Added header variables for NROWS, NCOLS and NCOMP to help standardize
1937   matrix files.  This functionality has been incorporated into
1938   rcollate, gendaymtx, and dctimestep.
1939 +
1940 + Created rmtxop utility to operate on multi-component matrices.  This
1941 + facilitates some daylight matrix calculations, and provides a general
1942 + tool for manipulating matrix data.
1943 +
1944 + ****** COMPATIBILITY CHANGE ********
1945 + Introduced new Hessian-based error control in irradiance caching (ambient)
1946 + calculation.  Since the format of the stored ambient values is different,
1947 + the old files will be rejected with an error message and must be removed.
1948 + The programs may be compiled with the -DOLDAMB option if this is a problem.
1949 +
1950 + Added -p option to rcontrib to set function file parameters on a per-modifier
1951 + basis to simplify bin evaluation.
