    Formulas in the B column multiply values from the A column using relative references, and the formula in B4 uses the SUM() function to find the sum of values in the B1:B3 range. A formula identifies the calculation needed to place the result in the cell it is contained within. A cell containing a formula, therefore, has two display components ...

    From its first version Excel supported end-user programming of macros (automation of repetitive tasks) and user-defined functions (extension of Excel's built-in function library). In early versions of Excel, these programs were written in a macro language whose statements had formula syntax and resided in the cells of special-purpose macro ...

    Given two sets and , let be a multivalued map from to (equivalently, : is a function from to the power set of ).. A function : is said to be a selection of , if: (() ()).The existence of more regular choice functions, namely continuous or measurable selections is important in the theory of differential inclusions, optimal control, and mathematical economics.

    In the table code, one must leave out the cells that are covered by such a span. The resulting column- and row-counting must fit. Tables can have cells spanning multiple rows, using |rowspan=n. The number of rows must be indicated with each use of rowspan. Before any sorting can be done, the rowspan setup must be correct. The wikitext must be ...

    In reverse Polish notation, [7] also known as postfix notation, all operations are entered after the operands on which the operation is performed. Reverse Polish notation is parenthesis-free, which usually leads to fewer button presses needed to perform an operation. By the use of a stack, one can enter formulas without the need to rearrange ...

  9. Function space - Wikipedia

    en.wikipedia.org/wiki/Function_space

    In mathematics, a function space is a set of functions between two fixed sets. Often, the domain and/or codomain will have additional structure which is inherited by the function space. For example, the set of functions from any set X into a vector space has a natural vector space structure given by pointwise addition and scalar multiplication.
