DCOMPLEX DCOMPLEX Convert to Double Precision (deprecated)

Usage

The dcomplex function used to convert variables into 64-bit
complex data types in prior versions of FreeMat.  Starting with FreeMat 4,
the type rules are the same as Matlab, hence, there is no distinction
between a 64-bit complex type and and 64-bit real type.  Thus, the dcomplex
function is just a synonym for double.
