MATLAB: Execute multiple statements within an ‘if’ construct

Question

I am trying to set properties of 3 textbox based on the state of a radiobutton. If the radiobutton is selected, I want the textboxes to be grayed so the user cannot enter values. My code works if I set only one textbox. However, I can't get it to change all of teh textboxes at the same time. Here is my code so far:

if (get(handles.radiobutton1 ,'Value') == get(handles.radiobutton1 ,'Max'))
    set(handles.edit4,'Enable','off', 'BackgroundColor', 'gray') 
    set(handles.edit5,'Enable','off', 'BackgroundColor', 'gray')
    set(handles.edit6,'Enable','off', 'BackgroundColor', 'gray')
else
    set(handles.edit4,'Enable','on', 'BackgroundColor', 'white')
    set(handles.edit5,'Enable','on', 'BackgroundColor', 'white')
    set(handles.edit6,'Enable','on', 'BackgroundColor', 'white')
end

Is there a way to use "set" to apply to more than one function handle at a time? Or why I can't I have multiple statements within my "if"?

Thank you in advance!

Answer 1

Use either RGB triplets (e.g. [1 0 0] for red) or one of the letters abbreviated in:

doc linespec

e.g. 'r' for 'red'

ps: gray using grb triplets will have all three (R,G,B) values the same:

e.g. 24 shades of gray:

gray(24)
