The problem is simple to state but quite a bit more complicated than you might expect. If you were to highlight the method name plot in a file and press Ctrl-D, which version of that function should it open? There are:
d = which('-all', 'plot')
35 different functions and/or methods by that name just in MathWorks toolboxes accessible on MATLAB Online. It is not always going to be possible to determine just through static analysis of the code around that call which of those functions Ctrl-D should open.
You could, if you had a variable in the workspace and were willing to modify your workflow a little, take advantage of a fairly little-used feature of the which function. If you specify an expression that calls a method, like the plot method on a graph object as the example below does, you can limit which methods are returned.
w = which('-all', 'plot(g)')
w =
{'/MATLAB/toolbox/matlab/graphics/math/@graph/plot.m'}
{'built-in (/MATLAB/toolbox/matlab/graph2d/plot)' }
This only returned two of the 35 plot functions and/or methods. Without the '-all' option only the first of those would have been returned, as per the following example.
dbtype('1:5', which('plot(g)'))
1 function p = plot(varargin)
2 % PLOT Plots an undirected graph
3 %
4 % PLOT(G) plots the undirected graph G.
5 %
You could copy that method call to the clipboard and write a shortcut or favorite that uses clipboard('paste') into a which call to determine the correct method to open then opens it with edit.
