BLAS and libU77 libraries Calling libU77 and BLAS routines EXTERNAL FLUSH See “EXTERNAL (statement and attribute)” on page 324 for a description of the EXTERNAL statement and attribute. As noted in the description, the attribute form of EXTERNAL cannot be used with subroutines, which must therefore be specified in the statement form. Man pages You can get detailed, online information for any libU77 or BLAS routine by using the man command to display an online reference page for that routine. The command-line syntax for the man command is: man section_number routine_name where section_number is either 3f (for libU77) manpagesor3x (for BLAS); and routine_name isthenameofthelibU77 or BLAS routine. For example, to display the man page for the libU77 routine FLUSH, give the command: $ man 3f flush TodisplaythemanpagefortheBLASroutineSAXPY, give the command: $ man 3x saxpy Two of the BLAS man pages provide general information about the BLAS routines: blas1(3x) describes basic vector operations, and blas2(3x) describes basic matrix operations. 610 Chapter 12
libU77 routines BLAS and libU77 libraries libU77 routines Table 12-2 lists the libU77 routines by category, and Table 12-3 briefly describes each routine, including signature and argument information. The sizes of the data types listed in Table 12-3 are the default sizes, unless indicated otherwise. See Table 3-1 for the sizes of the default data types.
