I have a lot of radiobuttons that i want to enable and disable depending on the contex of a txt file. I want to use a general function for that.
I have a text which i load to my code like 2 independent arrays.
If the content of array Value(i,1) is 0, then disable the appropriate radio button (handlesChannels(i,1).
The second array contains the handlers.
For example,the form of the content of the first element is: handles.radiobutton1 etc.
my code is like that:
formatSpec = '%f%s%[^\n\r]';
% Allocate imported array to column variable names
Value = dataArray{:, 2};
handlesChannels = dataArray{:, 3};
for i=1:68
if Value(i,1)=1;
set(handlesChannels{i,1},'enable','on')
else
Value(i,1)=0;
set(handlesChannels{i,1},'enable','off')
end
end
the error i get is :
Error using set
Value must be a handle
Is it even possible to do something like that? Any ideas? Thanks a lot!

filo - what is the third column of dataArray as you seem to be assuming that these values are handles to the radio buttons? How and where is this variable being initialized? (Note that the error message is telling you that the third column is not composed of handles to graphics objects.)
