Waitbar error during calculation
显示 更早的评论
Hello,
if I press button "x"- that I want to close waitbar for example during for i=1:a during calculation, I got error, why?
The second argument must be a message string or a handle to an existing waitbar.
Error in ==> Simulator>pushbutton5_Callback at 2543
waitbar(step/steps,calculation,sprintf([calculation,' %d%%
...'],round(step/steps*100)));
This is my code:
calculation = waitbar(0,'Calculation...','Name','Status of calculation');
for i=1:a;
step = 1+step;
waitbar(step/steps,calculation,sprintf([actual caltulation,' %d%%...'],round(step/steps*100)));
end;
for i=1:b;
step = 1+step;
waitbar(step/steps,calculation,sprintf([actual caltulation,' %d%%...'],round(step/steps*100)));
end;
for i=1:c;
step = 1+step;
waitbar(step/steps,calculation,sprintf([actual caltulation,' %d%%...'],round(step/steps*100)));
end;

It was not expecting you to close it after you set it up and tried to use it again. To avoid the error message, wrap the call to waitbar in a try catch
try
waitbar(step/steps,calculation,sprintf([actual caltulation,' %d%%...'],round(step/steps*100)));
catch
% Don't do anything in the catch, just ignore the error.
end
