Trace variables of a function when executing
显示 更早的评论
I have a matlab UI and it is desired to update the progressbar of this UI based on a variable which is being used in a running code ina function.
Consider below example:
%% a UI Code:
currentProg = min(round((size(wbar,2)-2)*(i/n)),size(wbar,2)-2);
RGB = app.processDataButtonHandle.Icon;
RGB(2:end-1, 2:currentProg+1, 1) = 0.25391; % (royalblue)
RGB(2:end-1, 2:currentProg+1, 2) = 0.41016;
RGB(2:end-1, 2:currentProg+1, 3) = 0.87891;
app.processDataButtonHandle.Icon = RGB; % (royalblue)
where
i
is a variable which shall be real time value of iterations in a for loop used in a function.
So, the whole code can be seen as:
%% a UI Code:
currentProg = min(round((size(wbar,2)-2)*(i/n)),size(wbar,2)-2);
RGB = app.processDataButtonHandle.Icon;
RGB(2:end-1, 2:currentProg+1, 1) = 0.25391; % (royalblue)
RGB(2:end-1, 2:currentProg+1, 2) = 0.41016;
RGB(2:end-1, 2:currentProg+1, 3) = 0.87891;
app.processDataButtonHandle.Icon = RGB; % (royalblue)
my_function(m,n,...)% other input variables
where in my_function() we have:
function my_function(m,n,...)% other input variables
for i=1:n
%% do some thing based on m
end
end
Do we have any possible way of updating that progress bar based on variable i which is in a for loop inside a function?

No, not without the cooperation of the function being executed or using the debug facilities, or the cooperation of some function called by the target function

The function itself could call waitbar(). Or a function that it calls could call waitbar(). Or you could use "dbstop at LINE if CONDITION" where you have coded CONDITION to invoke something that calls waitbar()
Note: there is an enhanced function that works like waitbar in the File Exchange, that also shows an estimate of time to completion
