I am trying to export a set of signals as Timeseries data using the Simulation Data Inpector (Matlab R2017b) to be used as an input to a Simulink model running R2022b. My current solution is to save it as a .mat file. I then want to use this data as an input for the model that I have updated to Matlab R2022b. I have tried using the 'signal editor block' to bring them in from the .mat loaded into the workspace, but that triggers the data incorrectly. I have tried using the 'from file' and 'from workspace' blocks but the .mat data saved from the Simulation Data Inspector has other data besides the signals and timeseries data. I know I could write a script to remove the unwanted data then use the 'from workspace' block, but I wanted to know if there is a quicker way to do this with the data as formated.

There are a few options that can be used to store simulation data from a Simulink model:

(1) [To File] to store data in .mat file: Timeseries or Array

(2) [To Workspace] and data type can be specified: Timeseries (by default), Array, Structure time series, Structure or Array

(3) [Scope]: Configuration Properties --> Logging --> Log data to workspace: Dataset, Structure time series, Structure or Array

You can choose which one best suits for your model.

But I want to take that .mat file (2017b) and import it to another simulink model running Matlab R2022b. Is there an easy way of loading this into the model? Right now I am looking at writing a script to pull out all the TS data from the .mat file then individually loading in the signals one at a time. (There are around 100 signals).
