How can i solve set problem?

 jPb = javax.swing.JProgressBar; set(jPb,'StringPainted','on','Value',0,'Indeterminate','off','Foreground',[0 0 1]);
        StatusBar(1)=uicontrol('Style','Text','Position',[.03*scrsz(3),.51*scrsz(4) .3*scrsz(3)15],'String','','BackgroundColor','w');
        [SB1, ~] = javacomponent(jPb,[.03*scrsz(3) .48*scrsz(4) .3*scrsz(3) 20],F1);
        % StatusBar2 - Pitch progression
        jPb = javax.swing.JProgressBar; set(jPb,'StringPainted','on','Value',0,'Indeterminate','off','Foreground',[0 0 1]);
        StatusBar(2)=uicontrol('Style','Text','Position',[.03*scrsz(3),.46*scrsz(4) .3*scrsz(3) 15],'String','','BackgroundColor','w');
        [SB2, ~] = javacomponent(jPb,[.03*scrsz(3) .43*scrsz(4) .3*scrsz(3) 20],F1);

And the error is:

Error using set Parameter must be scalar.

Error in GenDesign/UserInterface (line 95) jPb = javax.swing.JProgressBar; set(jPb,'StringPainted','on','Value',0,'Indeterminate','off','Foreground',[0 0 1]);

The javacomponent function is undocumented and will change in a future release. I do not recommend using it.

With regard to the error, this is because the types for your inputs do not match what that Java object is expecting. It expects a boolean, int, boolean, and Color respectively.

 set(jPb,'StringPainted',1,'Value',0,'Indeterminate',0,'Foreground',java.awt.Color(0,0,1));
