Get value from field

I want to create an entryfield and read the numeric value in it. Icreated the field but cant get the number from it.

Value is a property of the edit field. Access it using dot notation. You can see examples here: https://www.mathworks.com/help/matlab/ref/uieditfield.html

There are a couple ways of creating edit fields. What does your code look like?

[Mohammad Mohammad]

thresholdField = uieditfield(fig, 'numeric', 'limits', [0, inf]);
    thresholdField.Position = [0.25, 0.3, 0.1, 0.05];
    thresholdValue = thresholdField.Value;
        % Check if the threshold value is valid
        if isnan(thresholdField.Value)
           errordlg('Invalid threshold value. Please enter a numeric value.', 'Error', 'modal');
            return;
        end

There doesn't seem to be anything wrong with this code, other than that you have no time to put in a value before it is retrieved.

Error using uieditfield

'limits' is not a valid STYLE for uieditfield. STYLE must be 'text' or 'numeric'.

Error in createGUI (line 35)

thresholdField = uieditfield(fig, 'numeric', 'limits', [0, inf]);

it gives this error

You would get that error if fig is a figure() instead of being a uifigure()
