Can you be more specific. You can do something like.

   A = int16(zeros(10,1));

but whether that is what you need depends.

Hi Wayne,

in newer versions you might write zeros(10, 1, 'int16'): esp. interesting for large arrays, since it doesn't generate a double array first and convert later but creates the int16 array directly.

And in older versions this works efficiently:

clear('A') % On demand only!

A(10, 1) = int16(0);

Hi,

x = int32(42);
y = uint16(1);
