The elements and fields of arrays and structures must be compatible. You cannot pass arrays, character strings, or structures by value. You can pass arguments by value from f77 to C, but not from C to f77, since %VAL() is not allowed in a Fortran dummy argument list.FORTRAN...
Because vector operations cannot be expressed directly in the compiler, the compiler must be capable of transforming scalar operations into equivalent vector operations. The candidates for vectorization are operations in loops and assignments of structures. Compiler directives may be used to control vectori...
Problem dependence: Fortran excels at array processing. If your problem can be described in terms of simple data structures and in particular arrays, Fortran is well adapted. Fortran programmers end up using arrays even in non-obvious cases (e.g. f...

To free memory for structures created using this function, callmxDestroyArrayonly on the structure array. Do not callmxDestroyArrayon the arraypvaluepoints to. If you do, then MATLAB®attempts to free the same memory twice, which can corrupt memory. ...
This flag does not alter the layout of data in COMMON blocks or user-defined structures. Use with -dalign to enable added efficiency with multi-word load/stores. If used, all routines must be compiled with this flag. -depend[={yes|no}]...

Widespread use of vector pipeline supercomputers is restricted due to the machine-dependent task of vectorization. Though automatic vectorizers can be used to produce machine-dependent vectorized code from Fortran 77 code, algorithms and structures have to be carefully designed to allow efficient ...
