y = isfixed(a) y = isfixed(T) y = isfixed(q)

y = isfixed(a) returns 1 when the DataType property of fi object a is Fixed, and 0 otherwise.

y = isfixed(T) returns 1 when the DataType property of numerictype object T is Fixed, and 0 otherwise.

y = isfixed(q) returns 1 when q is a fixed-point quantizer, and 0 otherwise.
