  2. GNU Octave - Wikipedia

    en.wikipedia.org/wiki/GNU_Octave

    Elements can be referenced without creating a new variable by cascaded indexing, e.g. [1:10](3); Strings can be defined with the double-quote " character as well as the single-quote ' character; When the variable type is single (a single-precision floating-point number), Octave calculates the " mean " in the single-domain (MATLAB in double ...

  3. MATLAB - Wikipedia

    en.wikipedia.org/wiki/MATLAB

    Variables are defined using the assignment operator, =. MATLAB is a weakly typed programming language because types are implicitly converted. [35] It is an inferred typed language because variables can be assigned without declaring their type, except if they are to be treated as symbolic objects, [36] and that their type can change.

  4. External variable - Wikipedia

    en.wikipedia.org/wiki/External_variable

    In B, all variables must be declared, as one of auto, extrn, or implicitly as function arguments. [1] An external variable is defined outside functions, has a lifetime of the whole program execution, and introduced to function by the mean of extrn declaration. Using the following code in the tutorial as an example: [1]

  5. Iterator - Wikipedia

    en.wikipedia.org/wiki/Iterator

    MATLAB supports both external and internal implicit iteration using either "native" arrays or cell arrays. In the case of external iteration where the onus is on the user to advance the traversal and request next elements, one can define a set of elements within an array storage structure and traverse the elements using the for-loop construct ...

  6. Variable (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Variable_(mathematics)

    For example, in the notation f(x, y, z), the three variables may be all independent and the notation represents a function of three variables. On the other hand, if y and z depend on x (are dependent variables) then the notation represents a function of the single independent variable x. [24]

  7. Variable (computer science) - Wikipedia

    en.wikipedia.org/wiki/Variable_(computer_science)

    If a variable is only referenced by a single identifier, that identifier can simply be called the name of the variable; otherwise, we can speak of it as one of the names of the variable. For instance, in the previous example the identifier "total_count" is the name of the variable in question, and "r" is another name of the same variable.

  8. Object-oriented programming - Wikipedia

    en.wikipedia.org/wiki/Object-oriented_programming

    For example, class Employee might inherit from class Person. All the data and methods available to the parent class also appear in the child class with the same names. For example, class Person might define variables "first_name" and "last_name" with method "make_full_name()".

  9. Nested function - Wikipedia

    en.wikipedia.org/wiki/Nested_function

    Nested functions can be used for unstructured control flow, by using the return statement for general unstructured control flow.This can be used for finer-grained control than is possible with other built-in features of the language – for example, it can allow early termination of a for loop if break is not available, or early termination of a nested for loop if a multi-level break or ...
