%DOUBLE Convert to double precision. % DOUBLE(X) returns the double precision value for X. % If X is already a double precision array, DOUBLE has % no effect. % % DOUBLE is called for the expressions in FOR, IF, and WHILE loops % if the expression isn't already double precision. DOUBLE should % be overloaded for all objects where it makes sense to convert it % into a double precision value. % % See also SINGLE, DATATYPES, ISFLOAT, ISNUMERIC. % Copyright 1984-2004 The MathWorks, Inc.
