MATLAB: How to control fixed point rounding and other FIMATH settings from basic Simulink blocks using Simulink Fixed Point 6.2 (R2009b)

Question

When I am using the Embedded MATLAB block, I have control over rounding and other settings when doing multiplication and other operations in fixed point.

I would like to have the same control when using basic Simulink blocks and Stateflow charts.

Answer 1

The ability to control the fixed point rounding and other FIMATH settings using Simulink Fixed Point 6.2 (R2009b) is not available in basic Simulink blocks and Stateflow charts respectively.

As a possible work around, use an Embedded MATLAB block in Simulink, or an Embedded MATLAB Stateflow function.
