Section: FreeMat External Interface
ctypefreeze function is used to convert a FreeMat structure into
a C struct as defined by a C structure typedef. To use the cstructfreeze
function, you must first define the type of the C structure using the
ctypedefine function. The ctypefreeze function then serializes
a FreeMat structure to a set of bytes, and returns it as an array. The
usage for ctypefreeze is
byte_array = ctypefreeze(mystruct, 'typename')
where mystruct is the array we want to 'freeze' to a memory array,
and typename is the name of the C type that we want the resulting
byte array to conform to.
