Get and set Simulink model data from Matlab?
显示 更早的评论
I have a simple model with 1 input and output. The input it directly linked to the output. I was wondering if there was any way I could get the input name, set a value to it, run it and see if the output matches the input. I want to try and do this from an .M file if possible. Thanks!

Perhaps this explanation of the get_param and set_param commands will help. You could use get_param and set_param from within a mfile that uses the sim command to run the simulation. If your input and output are scalars, just take their difference in the mfile after the sim command. If they are time series,
isDifferent = sum(myInput - myOutput) ~= 0 ;

Glad it was useful. I will mention that Phil Goddard's tutorials helped me learn how to do this sort of thing, http://www.goddardconsulting.ca/software-tutorials.html#Simulink

If you are doing this from inside a Matlab script, you could use the disp command (http://www.mathworks.com/help/techdoc/ref/disp.html) to display the value returned by get_param at the Matlab prompt. Or you could make a GUI to show it but I don't know the details.

Lucas: You can use the Inport/Outport blocks to import/export data using the "Data Import/Export" pane of the model's Configuraion Parameters window. See here for more explanation: http://www.mathworks.com/help/toolbox/simulink/ug/bsuwmmp.html
