matlab GOTO (sort of)

I have a long script calling many other scripts that spit out a lot of figures.

For debugging purposes I think it would be useful if -when clicking on a picture- the editor goes to a specific line. Does anyone know if this is possible?

I thought I could implement something like

A=[];
figure
plot(x)

A=ginput(1)

if A~=[]
  goto(pointer,line)
end

The problem is that it only would work only right after that the figure is made. Not at the end of the analysis when I take a look to the figures for eventual errors.

In other words: is there a way to go to a specific line of the code by clicking on a figure?

N.B. For an implementation of GOTO see (GOTO FileExchange)

Solution

  • Try using the opentoline function in conjunction with a callback. Something like

    plot(1:10); % A simple plot
set(gcf,'ButtonDownFcn',@(h,e)opentoline('YourFunctionName.m',LineNumber));

    In this case, when you click on the figure (not the axis, or any labels, but the grey part of the figure) the m file will open in the editor to the line specified.

    If you want to programmatically determine the line number then do the following

    plot(1:10)
st = dbstack;
set(gcf,'ButtonDownFcn',@(h,e)opentoline(st(1).file,st(1).line-1));
