: describes the Fortran format code for printing the elements of the matrix A
. The format code may be any allowed on the system, whether it is standard Fortran or not. It may or may not be enclosed in brackets.
In addition, there are the following special codes which force X04CFF to choose its own format code:
- X04CFF will choose a format code such that numbers will be printed with an F8.4, an F11.4 or a 1PE13.4 format. The F8.4 code is chosen if the sizes of all the matrix elements to be printed lie between and . The F11.4 code is chosen if the sizes of all the matrix elements to be printed lie between and . Otherwise the 1PE13.4 code is chosen.
- X04CFF will choose a format code such that numbers will be printed to as many significant digits as are necessary to distinguish between neighbouring machine numbers. Thus any two numbers that are stored with different internal representations should look different on output. Whether they do in fact look different will depend on the run-time library of the Fortran compiler in use.
By preceding the desired format code by the string ‘MATLAB’, X04CFF will print the matrix such that it can be input into MATLAB, and TITLE
will be used as the name of the matrix.
