Foreach Operator (Solver Foundation)
Evaluates an expression for each possible combination of values of some iterator variables, and returns all the results.
Foreach[iters..., expr]
Example
Plus[Foreach[{p, Products}, x[p]]]
Plus[Foreach[{p, Products}, {s, Sources}, x[p, s]]]
Max[Foreach[{i, 5}, x[i]]]
Each iterator can be one of these forms:
{x, s} where s is a Set parameter. x is an iterator variable that takes the value of each element of the set in turn.
{x, n} where n is a number. x is an iterator variable that takes the values 0, 1, …, n-1.
{x, m, n} where m and n are numbers. x is an iterator variable that takes the values m, m+1, …, n-1.
{x, m, n, j} where m, n, and j are numbers. x is an iterator variable that takes the values m, m+j, …, n-j.
{x, {a, b, … z}} where x is an iterator variable that takes the values a, b, …, z.
If no iterators are specified, Foreach just evaluates expr.
