Hy everybody, I would share soma variable from mat-file (workspace_invaso.mat) in AppDesigner, but I can't do it. I don't want to load the mat-file in every callback function. Best regard, Dario

    % code
  classdef Volume_invaso_1 < matlab.apps.AppBase
    % Properties that correspond to app components
    properties (Access = public)
        UIFigure                 matlab.ui.Figure
        UITable                  matlab.ui.control.Table
        VOLUMEUTILEDINVASOLabel  matlab.ui.control.Label
        CapacitTextAreaLabel     matlab.ui.control.Label
        CapacityTextArea         matlab.ui.control.TextArea
        Button_Filo_Teso         matlab.ui.control.Button
        Button_Rippl             matlab.ui.control.Button
        Button_Peaks             matlab.ui.control.Button
    end
    properties (Access = private)
        load workspace_invaso.mat % Share variables
    end
    methods (Access = private)
        % Code that executes after component creation
        function startupFcn(app)
            load workspace_invaso.mat;
            app.UITable.Data=[Q_serie.annuale,Ve,Qu,Vu,Vc];
            app.UITable.RowName={'Gennaio';'Febbraio';'Marzo';'Aprile';'Maggio';...
    'Giugno';'Luglio';'Agosto';'Settembre';'Ottobre';'Novembre';'Dicembre'};
        end
