Section: Type Conversion Functions
The 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 Here is an example of a typecast from a float to an 8-bit integer
--> 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
