Model the exponential that your fixed-point project will be using, and
use it with the class embedded.fi. Or cast the embedded.fi object to
floating point and do an exponent on that -- but only if it accurately
models what your embedded software's going to do.

hi
i m trying out fixed point modelling via the 'fi' function in matlab.
everything seems smooth until i tried to exponent the 'fi' object.
error msg: 'function exp is not defined for values of class
embedded.fi'
applying the exponential function, 'exp', is essiential for my
project. anyone knows how to get ard this prob?
cheers
