Read variable values from m-file

I work on a simulation project containing a large simulink model. Before I could load the input variables to the model directly to the base workspace from a large mat-file. For several reasons we had to change the input file format from .mat to .m. The input variables are each stored in one separate m-file. To read the variables to the base workspace I just run the m-files. Each m-file contains one signal name together with the corresponding simulation values in matrix form. Ex: signalA.m; signal_A = [1 3;2 5;....]; The first column is the time stamp values.
My problem is not to read the variables to the workspace but to obtain the stop time value in the signal matrix. I need the last time value in order to activate the simulink model with the correct simulation time from a main function. Before I could just read the last time stamp value from one signal from the mat-file. Does anyone have any idea how to read the signal values from the m-file in order to obtain the last time stamp value?

I don't understand. Don't you have a line in your m-file that says something like
lastStopTime = signal_A(42);
???
Or do you have a scope problem where you need to call assignin(), evalin(), or something like that?

The problem seems to be that the simulation wants its inputs in terms of many separate m-files, but that it is easier to work with a single data saved in a single mat-file. What about using a mat-file for everything you have control of and writing a wrapper to create the m-files the simulation wants. Just because one stage wants data in an efficient manner, doesn't mean your entire workflow needs to suffer.
