Hi Radu,
To read variable values from a .TXT file and set your MATLAB App Designer properties to these values, you need to ensure that the reading and assignment operations are correctly implemented.
Below is a step-by-step guide to achieve this:
1. Read the Variables from the .TXT file:
Use MATLAB functions like fopen, fgetl, fscanf, or textscan to read the values from the .TXT file.
2. Assign the Values to App Properties:
Ensure that the properties you want to set are defined in your app.
Assign the read values to these properties within a method or callback function.
Example Implementation:
Let's assume you have a .TXT file named 'variables.txt' with the following content:
sample1
sample2
sample3
You want to read these values and set them to properties 'Property1', 'Property2', and 'Property3' in your app.
- Define the Properties
Define the properties in your app class:
properties (Access = public)
Property1
Property2
Property3
end
2. Create a Method to Read the File and Set Properties
Create a method to read the file and set the properties:
methods (Access = private)
function readAndSetProperties(app)
% Open the file
fileID = fopen('variables.txt', 'r');
% Read the values
values = fscanf(fileID, '%f');
% Close the file
fclose(fileID);
% Set the properties
if length(values) >= 3
app.Property1 = values(1);
app.Property2 = values(2);
app.Property3 = values(3);
else
error('The file does not contain enough values.');
end
end
end
3. Call the Method
Call the `readAndSetProperties` method at an appropriate place in your app, such as in the `startupFcn` or in response to a user action like pressing a button.
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
app.readAndSetProperties();
end
% Button pushed function
function ReadFileButtonPushed(app, event)
app.readAndSetProperties();
end
end
Hope it helps!
