Load File into a Block

Hi All,

I am trying to load an excel file that contains my S-Parameter data into a "General Passive Network" using a GUI. I see that the General Passive Network has a location for "Data File" but I dont knwo how to pass the file to this spot.

I am able to open the file using

    handles.fileName= uigetfile('.xls')
    guidata(hObject,handles)
    fileName = handles.fileName;

But not sure how to do the next step (load into SIMULINK block). Any help is greatly appreciated!

If you select the block then type

   get_param(gcb,'DialogParameters')

into MATLAB it will tell you the options you can change via get/set param. In this case I saw File had the file name. So you would do something like

   set_param(gcb,'File',fileName)

Not sure how well this will work in that block though, it doesn't look like it expects an xls file, but a s2p type file.

Ryan,

Thank you for the very useful info. You are correct- I learned this week that this block does not take Excel files but raw SA files (S2p etc). Appreciate the help.
