Convert fi object to unsigned 8-bit integer
c = uint8(a)
c = uint8(a) returns the built-in uint8 value of fi object a, based on its real world value. If necessary, the data is rounded-to-nearest and saturated to fit into an uint8.
This example shows the uint8 values of a fi object.
a = fi([-pi 0.5 pi],0,8); c = uint8(a) c = 0 1 3
