In computer programming, array slicing is an operation that extracts a subset of elements from an array and packages them as another array, possibly in a different dimension from the original. Common examples of array slicing are extracting a substring from a string of characters, the " ell " in "h ell o", extracting a row or column from a two ...
In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.
F retains the array features added in Fortran 90, and removes control statements that were made obsolete by structured programming constructs added to both FORTRAN 77 and Fortran 90. F is described by its creators as "a compiled, structured, array programming language especially well suited to education and scientific computing". [ 71 ]
For example, an array containing 100 elements, each of which occupies 32 bytes, requires 100 × 32 bytes. By itself, such a memory block has no place to keep track of how large the array (or other object) is overall, how large each element within it is, or how many elements it contains. A dope vector is a place to store such information.
New Fortran statements, such as FORALL, and the ability to create PURE (side effect free) procedures; Compiler directives for recommended alignment and distribution of array data (influenced by the earlier Fortran D [1] [2] and Vienna Fortran research efforts) Compiler directive for specifying processor arrangements (e.g., rank, extent, etc.)
The following C99 function allocates a variable-length array of a specified size, fills it with floating-point values, and then passes it to another function for processing. Because the array is declared as an automatic variable, its lifetime ends when read_and_process() returns.

Silverfrost FTN95: Fortran for Windows is a compiler for the Fortran programming language for computers running Microsoft Windows. It generates executable programs from human-written source code for native IA-32 Win32, x86-64 (from version 8.00 [1]) and for Microsoft's .NET platform. There is a free-of-charge Personal edition, which generates ...
