Question about run executable(Generated by simulink code) in cmd

Hello,

I was learning the example "Run Batch Simulations Without Recompiling Generated Code" in help documentation.

In the M file, there are two sentences:

runstr = ['.', filesep, 'rtwdemo_rsimtf -p params',num2str(i),'.mat', ' -v'];
runstr = ['.', filesep, 'rtwdemo_rsimtf -f rsim_tfdata.mat=sweep', ...
            num2str(i),'.mat -v -tf 4.096'];

My question is about these 2 sentences:

1. what's the function of '.' at the start the bracket?
2. what do '-p', '-v' and '-f' mean?

Thanks!

[Li Huang]

3. What does "-tf" mean?

Answer 1

The '.' means "relative to the current directory".

For your other questions, see: https://www.mathworks.com/help/rtw/ug/rapid-simulations.html#f6817

-f is "Read input data for a From File block from a MAT-file other than the MAT-file used for the previous simulation"

-p is "Read a parameter vector from file filename.mat"

-v is "Run in verbose mode"

-tf is "Run the simulation until the time value stoptime is reached"
