When you export data from the Signal Builder in R2011b, it exports it as a structure with all kinds of Signal Builder-specific information. Unfortunately, the Signal Builder cannot import that kind of structure.
If you open the doc page for importing with this command, you can see that you need to have a cell array or structure with time to import the data like you want:
>> web([docroot '/toolbox/simulink/ug/f15-109640.html'])
I think the easiest thing to do is:
- Copy the Signal Builder to a new model
- Connect the Signal Builder output to a To Workspace block
- Change the To Workspace block to save a "Structure with time" to the workspace
- Save the variable output by the To Workspace block to a MAT-file
- Import that MAT-file to the Signal Builder
You could also just modify the variable exported by the Signal Builder, but I think this model approach is a bit easier/straightforward.
