Section: Type Conversion Functions
cast function allows you to typecast a variable from one
type to another. The syntax for its use is
y = cast(x,toclass)
where toclass is the name of the class to cast x to. Note
that the typecast must make sense, and that toclass must be
one of the builtin types. The current list of supported types is
'cell' for cell-arrays
'struct' for structure-arrays
'logical' for logical arrays
'uint8' for unsigned 8-bit integers
'int8' for signed 8-bit integers
'uint16' for unsigned 16-bit integers
'int16' for signed 16-bit integers
'uint32' for unsigned 32-bit integers
'int32' for signed 32-bit integers
'uint64' for unsigned 64-bit integers
'int64' for signed 64-bit integers
'float' for 32-bit floating point numbers
'single' is a synonym for 'float'
'double' for 64-bit floating point numbers
'char' for string arrays
--> cast(pi,'uint8') ans = 3
and here we cast an array of arbitrary integers to a logical array
--> cast([1 0 3 0],'logical') ans = 1 0 1 0
