Code causes error "index exceeds mtrix dnsion"

[Ngchris]

Please help - code causes error "index exceeds mtrix dnsion"

count11_norm=cumsum(count11)/max(cumsum(count11));

%outage probability


j1= 1;


for i1=find(SNR_dB==2):find(SNR_dB==20)

range11=0:0.1:max(c11_all);


count11=histc(c11_all,range11);
