MATLAB: How to select the data type for the transfer function block in Simulink

Question

I want to have a Transfer Function with fixed-point data types in Simulink. The Transfer Function block does not allow me to select the data type.

Answer 1

This enhancement has been incorporated in Release 2009b (R2009b). For previous product releases, read below for any possible workarounds:

The ability to select the data type for the Transfer Function block is not available in Simulink.

As a workaround, the 'Digital Filter' block from the Signal Processing Blockset can be used which allows using data types other than double.
