Programatically Created Random Signal Generator

Sorry if this deviates significantly from what you currently have, but here is an example of a signal generator that passes the individual fields as inputs into the callback function. Also the str2double() function was used to parse the values of the uieditfields.

          %App figure properties% App = uifigure(); App.Name = "Random Signal Generator"; X_Position = 200; Y_Position = 220; Height = 300; Width = 650; App.Position = [X_Position Y_Position Width Height];  %Amplitude field% X_Position = 150; Y_Position = 245; Height = 30; Width = 90; AmplitudeEditField = uieditfield('Parent',App); AmplitudeEditField.Position = [X_Position Y_Position Width Height];  %Number of samples field% SamplesEditField = uieditfield('Parent',App); SamplesEditField.Position = [X_Position Y_Position-40 Width Height];  %Start range field% nRange1EditField = uieditfield('Parent',App); nRange1EditField.Position = [X_Position Y_Position-80 Width Height];  %End range field% nRange2EditField = uieditfield('Parent',App); nRange2EditField.Position = [X_Position Y_Position-120 Width Height];  Label_1 = uilabel('Parent',App); Label_1.Position = [X_Position-90 Y_Position Width Height]; Label_1.Text = "Amplitude";  Label_2 = uilabel('Parent',App); Label_2.Position = [X_Position-90 Y_Position-40 Width Height]; Label_2.Text = "Number of Samples";  Label_3 = uilabel('Parent',App); Label_3.Position = [X_Position-90 Y_Position-80 Width Height]; Label_3.Text = "Start of Range";  Label_4 = uilabel('Parent',App); Label_4.Position = [X_Position-90 Y_Position-120 Width Height]; Label_4.Text = "End of Range";  Label_Set = findall(App,'Type','uilabel'); Red = 0.2; Green = 0.2; Blue = 0.2; set(Label_Set,'BackgroundColor',[Red Green Blue]); set(Label_Set,'FontColor','white'); set(Label_Set,'FontSize',9); set(Label_Set,'HorizontalAlignment','center');  %Calculate button properties% Generate_Button = uibutton('Parent',App); X_Position = 60; Y_Position = 60; Height = 40; Width = 180; Generate_Button.Position = [X_Position Y_Position Width Height]; Generate_Button.Text = "Generate"; Red = 0.7; Green = 0.7; Blue = 0.7; Generate_Button.BackgroundColor = [Red Green Blue];   UIAxes = uiaxes(App); X_Position = 300; Y_Position = 50; Height = 220; Width = 300; UIAxes.Position = [X_Position Y_Position Width Height]; UIAxes.XLabel.String = 'Sample Index'; UIAxes.YLabel.String = 'Amplitude'; UIAxes.Title.String = 'Generated Signal';   Generate_Button.ButtonPushedFcn = @(Generate_Button,event) GenerateButtonPushed(AmplitudeEditField,SamplesEditField,nRange1EditField,nRange2EditField,UIAxes);   function GenerateButtonPushed(AmplitudeEditField,SamplesEditField,nRange1EditField,nRange2EditField,UIAxes)      amplitude = (AmplitudeEditField.Value);     samples = (SamplesEditField.Value);     n_range1 = (nRange1EditField.Value);     n_range2 = (nRange2EditField.Value);       if(amplitude ~= "" && samples ~= "" && n_range1 ~= "" && n_range2~= "")          amplitude = str2double(amplitude);     samples = str2double(samples);     n_range1 = str2double(n_range1);     n_range2 = str2double(n_range2);     n_range = linspace(n_range1,n_range2,samples);     xn = amplitude .* sin(2*pi*randn(1,samples));     stem(UIAxes,n_range,xn);      end  end
