Using the "To Workspace" block, many signals of different sampling time are saved to the workspace as "Structure with time". The results are saved in "simout". As the sampling time is different, the data consists of unequal length, and cannot be appended within a single array. Further, two logging intervals have been used.
I would like to combine the signals of sample rate 100ns, 1us, 15us and 150us so that the data for each logging interval can be retrieved in one go (or I would have to read each array (variable? - not sure of the term to be used)).
The time is stored in "tout" within "simout", and each signal is saved with the name specified in "To Workspace". The same is attached.
Is there a way to access these variables (arrays??) using some simplified method? I'm new to programming and not yet familiar with all the terms.

sorry to insist but why not resample (in your simulink file) all the data at the simulation sampling rate ? those who runs at slower sampling rate would have multiple values (interpolation) but that doesn't seem to be an issue IMO

@Mathieu NOE I've extracted the data at different sampling rates and have them in 6 separate tables. 3 are for logging interval one and the other three for logging interval two. Each variable in the table is a column vector.
While column heading in spreadsheets are read into MATLAB as variable name, the variable name is not converted to column heading in excel. Only the data (numerical values) are imported into .xlsx file (when table contents are copied and pasted in an .xlsx file).
Is there a way to export the variable names in a table to spreadsheet along with the values?

I would suggest you saving the data in time series format and use API to process it.

Thanks! This seems to be more simple.
