How to delete rows in matlab

So guys i need your help this is my code:

    a=3;
    lamda=1.54;
    in=-3:3;
    %calculate z
    [h,k,l]=meshgrid(in);
     d = sqrt((a.^2)/(h.^2 + k.^2 + l.^2));
     z = (lamda./(2*d));
     %sort absolute values ascending, which allows to use unique
     ac=sort(abs([h(:) k(:) l(:)]),2);
     %use unique to identify duplicates
     [f,g,h]=unique(ac,'rows');
     %count
     cnt=histc(h,1:max(h));
     disp([h(g),k(g), l(g),z(g),cnt])

i just want to delete or terminate rows containing z>=90, i can't used break because it only works in for loop or while loop,

so what other command may i use? thankas.

try something like this

% create a matrix with all vectors
M = [h(g),k(g), l(g),z(g),cnt];

% define the threshold for z
threshold = 0.90;

% delete all lines with z>0.90
M(M(:,4)>threshold,:) = [];

if true
  % code this is the output i want
h  k  l  z  cnt
