The MATLAB® API provides a set of functions that support
signed and unsigned 8-, 16-, and 32-bit data. For example, the
constructs an unpopulated N-dimensional numeric array with a specified
data size. For more information, see
Once you have created an unpopulated MATLAB array of a
specified data type, you can access the data using
These two functions return pointers to the real and imaginary data.
You can perform arithmetic on data of 8-, 16-, or 32-bit precision
in MEX files and return the result to MATLAB, which recognizes
the correct data class.
2 matrix with unsigned
16-bit integers, doubles each element, and returns both matrices to MATLAB.
To build this example, at the command prompt type:
Call the example.
ans = 2 6 4 8
The output of this function is a
populated with unsigned 16-bit integers.
