Visualize (plot) 3D array data

Surf and mesh functions are not handling the following data. Is it me or other methods should be used ? Thanks

ts=5;
t=0:1/ts:1;
x1U=0.35; % in m
x1L=0.20; % in m
x2U = deg2rad(150);
x2L = deg2rad(120);
x3U = deg2rad(-150);
x3L = deg2rad(-120);
x1=x1L:(x1U-x1L)/ts:x1U;
x2=x2L:(x2U-x2L)/ts:x2U;
x3=x3L:(x3U-x3L)/ts:x3U;
[xx1,xx2,xx3] = meshgrid(x1,x2,x3);
zz1 = 0*xx2;
zz2 = 0*xx2;
zz3 = 0*xx3;
for idx = 1:length(x1)
    for jdx = 1:length(x2)
        for kdx =1:length(x3)
            xijk = [x1(idx) ;x2(jdx);x3(kdx);t(kdx)];
            out = PRSopt_QN1(xijk);
            zz1(idx,jdx,kdx) = out(1);
            zz2(idx,jdx,kdx) = out(2);
            zz3(idx,jdx,kdx) = out(3);
        end 
    end 
end 
figure ()
mesh(xx1,xx2,zz1)
hold on
surf(xx1,xx2,zz2)

It looks like your zz2 is a 3D matrix. Either plot one matrix at time using surf or read about Slice.
