Hi,
I am using the diary function to log my application output. Something like

diary(path_to_logfile)
% all my code with output to the console, matrices written to desk, etc
diary off

When the code fails, the diary is not closed. One option would be to wrap all the code on a try-catch statement and close it on the catch.

Is there another way to avoid the diary being "open" when the app fails?Hi,

I do a lot long running scripts that plot to multiple figure.

Hi team
I am using EODHD.COM for stock data. I get the following error every now and then. example – if I am iterating over say 50 stocks data, the code sometimes throw an error for 1 stock, then I rerun the full script allover again and it will work. I used webread to start with but webread doesn’t even read the webpage and returns no data (urlread returns data instead).
Error using urlreadwrite_legacy (line 88)
The IP address of "eodhd.com" could not be determined.
Error in urlreadwrite (line 88)
[output,status] = urlreadwrite_legacy(fcn,catchErrors,varargin{:});
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in urlread (line 16)
[s,status] = urlreadwrite(mfilename,catchErrors,url,varargin{:});
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in NSE_all (line 78)
EOD_data = urlread(URL2); % json data
^^^^^^^^^^^^^

My codes are:
url2A = ‘https://eodhd.com/api/eod/’;
url2B = ‘?from=’;
url2C = ‘&period=d&api_token=’;
url2D = ‘&fmt=json’;
From = datetime("today") – (365 * 20);
dt_str = char(From);
URL2 = url2A + company + url2B + dt_str + url2C + token + url2D;
EOD_data = urlread(URL2);
*please note company is a name of the stock ticker I take from the list for the For loop so I iterate through multiple companies stocks.
Is it possible to tell urlread to wait longer and try more before throwing an error? or even keep trying for the specified time? I want urlread to not stop my script at any random time. I am new to Matlab so if anyone can help it would be great.Hi team

Hello there,
I’ve made a for loop for filling a struct with png images, this because i need to recall the same images a view times in my application. If i recall my images from the struct i get the images but there seems to be a jpg compression on the png file? This is how i load the struct:

imageDir = ‘Edwinfiles’; % Map met de afbeeldingen
imageExt = ‘.png’; % Extensie van de afbeeldingen

% Lijst van afbeeldingsnamen zonder extensie
imageNames = {‘edammer’, ‘edammer_selected’, ’emmentaler’, ’emmentaler_selected’, ‘beemster’, ‘beemster_selected’, …
‘gorgonzola’, ‘gorgonzola_selected’, ‘goudse’, ‘goudse_selected’, ‘gruyere’, ‘gruyere_selected’, ‘manchego’, …
‘manchego_selected’, ‘noordwoudse’, ‘noordwoudse_selected’, ‘roquefort’, ‘roquefort_selected’, …

‘erik2′,’erik3′,’erik4′,’erik5′,’erik6′,’erik7’};

% Loop door de lijst van afbeeldingsnamen en laad de afbeeldingen
for i = 1:length(imageNames)
imageName = imageNames{i};
imagePath = [imageDir, imageName, imageExt];
app.imageStruct.(imageName) = imread(imagePath,"png", ‘BackgroundColor’, [0.94 0.94 0.94]);
end
imageStructfile = app.imageStruct;
save("EdwinfilesimageStruct.mat",’imageStructfile’);
And when i load an image from the struct it looks like this:
app.image_Erik.ImageSource = app.imageStruct.erik0;
Can anyone tell me if i am doing something wrong.
If i load the image with app.image_Erik.ImageSource = imread(‘files/erik0.png’); then i don’t see any compression…

I have a small MATLAB project that I would like to use in many other MATLAB projects. And, I want to do this programmatically (as part of a build pipeline) instead of any sort of manual installation.
Typically, In Java world, for a similar situation, this is how it usually works:
I create a jar file out of this project that I want to share with other projects
I then push that jar file to a maven repository with a particular version as part of the build process (either hosted internally in an organization or an outside maven repository)
Other projects can then specify a particular version as a dependency for this jar in their pom.xml file and that is how the code gets available to them
What is the equivalent of workflow for above in MATLAB world?I have a small MATLAB project that I would like to use in many other MATLAB projects. And, I want to do this programmatically (as part of a build pipeline) instead of any sort of manual installation.
