You have put the k=k+1
at a wrong place. It is the correct code:
stab1=zeros(1,4991);
k=0;
for ii=-0.6:0.01:-.3
m=0;
for jj=0:0.01:1.6
m=m+1;
if .... (some condition)
stab1(k*161+m)=1;
end
end
k=k+1;
end
Now it has 4991 elements.
solved How many elements the output matrix should have in this code? [closed]
