hey,
I have a script I've wrote and during that script I'm turning on Datalogging of some model. Everything went fine when I build the model in Simulink by connect block's lines with the Mouse, But when I create a model with .m file with 'add_block' and 'add_line' commands then when I run the script I got an error says:
'No appropriate method, property, or field unpack for class Simulink.SimulationData.Dataset.'
This Error refer to the command: ' logsout.unpack('all');'
Thanks for helpers!

The default type for logsout is a Simulink.SimulationData.Dataset, which does not have an unpack method. The Simulink.ModelDataLogs type does. It sounds like you are using ModelDataLogs in your hand-built model, but a Dataset in your script-build one.

Is there an alternate way to unpack when using 'Dataset' ? I want to save the data logged by Signal logging into a MAT File and for that I wanted to use unpack('all')

As far as I know, there is no unpack equivalent for Datasets. (But you could always save the variable in the mat file without unpacking it.)
