basically i'm converting an idl syntax to MATlab the idl syntax is known as "fix" which "The FIX function converts a given expression to an integer type. Optionally, the conversion type can be specified at runtime, allowing flexible runtime type-conversion to arbitrary types."
i think its "real" but not sure if theres other alternatives
Thanks

Try int32():
intVariable = int32(doubleVariable);

It's actually not documented in matlab what the rounding behaviour of the intxx functions actually is. If it is the same as C, then it does indeed do the same as fix.

The fix function is also available in matlab, if that's what you're asking.
Type information is usually not important in matlab. It's got better in recent releases but there's still plenty of functions that don't work with integer types.
