sel=ef(demal,:);

Best Answer

If demal has zeros in it sel=ef(demal,:) cannot work.

Thank you Monkey, I really appreciate your help, but it seems that I've found a more effective solution:*

A=[1 3 2 4;  
   5 6 7 8;     
   9 1 2 3;     
   4 5 6 2]; 
R=[1 3 0 7];
B=zeros(7);
    RNZ=R(R ~= 0);   
    d=find(R);
    T=A(d,d');
    B(RNZ,RNZ')=T

Jacob - your arrays like

ef=[app.ef1.Value,app.ef2.Value,app.ef3.Value,app.ef4.Value,app.ef5.Value,app.ef6.Value,...
        app.ef7.Value,app.ef8.Value,app.ef9.Value,app.ef10.Value,app.ef11.Value,app.ef12.Value];

are just values and not handles to the objects that you want clear/reset. You might want to try storing the handles in each array like

ef=[app.ef1, app.ef2, app.ef3, app.ef4, app.ef5, app.ef6, ...
        app.ef7, app.ef8, app.ef9, app.ef10, app.ef11, app.ef12];

and then access these handles as

    for n=1:12
        if(p(n).Value == 0)
            ef(n).Value = '';
            r(n).Value = 0;
            b(n).Value = 0;
            f(n).Value = 0;
        end   
    end

I don't know if the above will work...and I suspect that there are alternatives to this...but give it a try.
