CAST Typecast Variable to Specified Type
Section: Type Conversion Functions
Usage
Thecast
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
Example
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
