What's the best way to write this code?

I'm doing some coursework on an aircraft fuel system controlled in simulink/matlab and I'm pretty new to Matlab.

Basically the conditions for this operation are that there needs to be either a main pump or aux pump running to feed fuel into each engine, of which there are two.

Is it possible to express this as (OR)(AND)(OR) like what I'm trying to do here and how would I write it?

while ((RFeedPump1Stat == 1) "OR" (RFeedPump2Stat == 1)) && ((LFeedPump1Stat == 1) "OR" (LFeedPump2Stat == 1)) 
    if (XFeedSwitch == 1)
        XFOpen = 1;
        REOpen = 0;
    elseif (XFeedSwitch == 2)
        XFOpen = 1;
        LEOpen = 0;
    else
        XFOpen = 0;
    end
end

thank you.

"OR" to be replaced with ||

with what sorry?

Change your code from this

 while ((RFeedPump1Stat == 1) "OR" (RFeedPump2Stat == 1)) && ((LFeedPump1Stat == 1) "OR" (LFeedPump2Stat == 1))

To this

 while ((RFeedPump1Stat == 1) || (RFeedPump2Stat == 1)) && ((LFeedPump1Stat == 1) || (LFeedPump2Stat == 1))
