Setting Look Up Table parameter 'Table' from GUI using set_param
显示 更早的评论
I want to set the LUT parameter 'Table' frm a GUI:
Lookup Table (n-D): ..... simulink library block
Table data: wArray
Breakpoints 1: ........
I am writing the following code in edit callback in GUI:
wNewVal = str2double(get(hObject,'String'));
w=wNewVal;
wArray=[w w 0 0 -1*w -1*w 0 0]
set_param('SDH/Tp/w','Table','wArray')
i can run the code without any errors but if i run my simulation..i get the following error:
Error evaluating parameter 'Table' in 'SDH/Tp/w'
Caused by:
Undefined function or variable 'wArray'.
See this also:
get_param('SDH/Tp/w','Table')
ans =
wArray

The code in the GUI Callback creates variables in the callback function workspace. Do you run the simulation from the function or independently? If you run it using the SIM command from the function, use this syntax:
options = simset('SrcWorkspace','current','DstWorkspace','current');
sim('mymdl', [0 duration], options)
Otherwise, make sure that the variable 'wArray' is created in the base workspace, because that's where the model looks for it:
wNewVal = str2double(get(hObject,'String'));
w=wNewVal;
wArray=[w w 0 0 -1*w -1*w 0 0];
assignin('base', 'wArray', wArray);
set_param('SDH/Tp/w','Table','wArray')

I have a simiar issue... How do you create a variable in the base workspace within the app?

For the above question, How will you set the values for Breakpoints. When I try to do that in a same way which was mentioned. I am getting the following error
Lookup_n-D block does not have a parameter named 'Breakpoints'.
It recognizes tabledata parameter but not breakpoints parameter. How to overcome that?

It is not named as 'Breakpoints'. Try the below command, bro. LookupTable = find_system(sys,'BlockType','Lookup_n-D'); get_param(LookupTable,'BreakpointsForDimension1')

'TableData' is the name for the table data if people are wondering
