DEAL Multiple Simultaneous Assignments

Section: Elementary Functions

# Usage

When making a function call, it is possible to assign multiple outputs in a single call, (see, e.g., `max` for an example). The `deal` call allows you to do the same thing with a simple assignment. The syntax for its use is

       [a,b,c,...] = deal(expr)

where `expr` is an expression with multiple values. The simplest example is where `expr` is the dereference of a cell array, e.g. `expr <– A{:}`. In this case, the `deal` call is equivalent to

       a = A{1}; b = A{2}; C = A{3};

Other expressions which are multivalued are structure arrays with multiple entries (non-scalar), where field dereferencing has been applied.
