You cannot. Variables in the workspace are dynamic, created at execution time, but when you are in the editor you are working statically.

The closest you could get would be to have function input parameter names pop-up as you are typing a reference to a function. In the above example, sfighandles has no input parameters, so nothing useful could be done for it.

I write the following codes,But still I have problem.

[h1,h2,h3,h4]=sfighandles;

function [h1 h2 h3 h4] = sfighandles;

%--------------------------------------------------------------------------

% Define small figure handles for drawing 4 graphs on screen:-

scrsz = get(0,'ScreenSize'); % tells us the screen size

% Use command: figure('Position', [left, bottom, width, height])

h1 = figure('Position',[1 scrsz(4)/2 scrsz(3)/2 scrsz(4)/2.4]);

h2 = figure('Position',[scrsz(3)/2 scrsz(4)/2 scrsz(3)/2 scrsz(4)/2.4]);

h3 = figure('Position',[1 4 scrsz(3)/2 scrsz(4)/2.4]);

h4 = figure('Position',[scrsz(3)/2 4 scrsz(3)/2 scrsz(4)/2.4]);

return;

在 MATLAB Online 中打开

I'm not exact sure what you are asking, so perhaps you can clarify.

You can declare a variable to be global

   >> global X
   >> X = randn(10,1);

Then inside a function

 function a = testsum
   global X
   a = sum(X);
 end

Note that X is not defined locally inside of testsum.m. I never feel comfortable personally with global variables and just pass what I need to the function.
