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.
