While it may be unsafe programming, I seem to generate a lot of code which would be far more readable without having to explicitly refer to the handles i'm passing. I'm looking for one of the side benefits of c#'s "using" statement I suppose.

An example:

Instead of:

handles.sqs(i) = handles.fs * 10 * handles.inf(i).RTImageSID ...
/ handles.inf(i).RadiationMachineSAD / handles.inf(i).ImagePlanePixelSpacing(1);

Is there a command that would let me just write:

handles.sqs(i) = fs * 10 * RTImageSID / RadiationMachineSAD ...
/ ImagePlanePixelSpacing(1);

Thanks!

No, there no command like that in Matlab.

As you are working in a loop with values extracted from the same
substructure, you can do something like this:

for K = 1:N
thisinf = handles.inf(i);
handles.sqs(i) = handles.fs * 10 * thisinf.RTImageSID /
thisinf.RadiationMachineSAD / thisinfo.ImagePlanePixelSpacing(1);
end

You could of course shorten the temporary structure name.

ahh, too bad.

good point.

thanks for the response!
