Hi, I have a problem here where I could not display my result of the equation in the text area.
Below is the code.
The app.EIRP.Value is the text area.
pt = app.ouputpower.Value;
lbo = app.backoffloss.Value;
lbf = app.eartbranchingloss.Value;
at = app.antennagain.Value;
lu = app.uplinkloss.Value;
lp = app.pathloss.Value;
gte = app.gteratio.Value;
bfb = app.satbranchingloss.Value;
br = app.bitrate.Value;
app.EIRP2 = pt+at-lbo-lbf;
app.EIRP.Value = num2str(eval(app.EIRP2));

It's unclear whether you're working with numeric or text values. App designer has edit fields that return text and edit fields that return numeric values.
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/253652/image.png)
If you're working with text edit fields that contain numeric characters such as '42', you must convert them to numeric, do the math, then convert the result back to character (or string). Consider replacing the text edit fields with numeric edit fields
pt = str2double(app.ouputpower.Value); % converts from string/char to double
app.EIRP.Value = num2str(app.EIRP2); % converts from numeric to char
% -or -
app.EIRP.Value = sprintf('%.3f',app.EIRP2); % converts from numeric to char
% No need for eval (Ever)
If you're working with numeric edit fields there is no need to do any conversion.
pt = app.ouputpower.Value;
app.EIRP.Value = app.EIRP2;

Hello,
as I am not much familiar with App Designer, I would ask for your help regarding a similar issue.
I have a button with a callback function, where I am doing my calculations. In the end I have some results I would like to display in the TexEdit Field.
avgDiff = mean(diff(timestamp')); %checking the acquisiton rate
fprintf('The average timestamp diff is %.3f\n', avgDiff)
Sync_rate = (S/5) * 100 ;
fprintf('The synchronization rate is: %.2f\n', Sync_rate )
How can I write in the end of the function that it displays these values?
app.status(end+1,1) = {'Sync rate is... and then to display : "Avg timestamp diff is"'};
set(app.StatusWindowTextArea,'Value',app.status)
set(app.StatusColour,'Background',[0 1 0])
end
pause(1)
Thank you in advance!

if you have a complex number vector just use:
evalc('anything')
Example:
someArray = [1 2 1 2];
theThingYouWantToShow = roots(someArray);
%theThingYouWantToShow is a vector with complex numbers (if you can show this, you can show anything :) (I guess) )
app.SomeTextArea.Value = evalc('theThingYouWantToShow');
