Question

下面程序运行时出错,该怎么改
echo on
Lc=20;
A1=3;
A2=7;
A3=12;
A4=0;
w0=1;
SNRindB=0:2:30;
for i=1:length(SNRindB),
smld_err_prb1(i)=ss_Pe94(SNRindB(i),Lc,A1,w0);
smld_err_prb2(i)=ss_Pe94(SNRindB(i),Lc,A2,w0);
smld_err_prb3(i)=ss_Pe94(SNRindB(i),Lc,A3,w0);
echo off;
end;
echo on;
SNRindB4=0:1:8;
for i=l:length(SNRingB4),
smld_err_prb4(i)=ss_Pe94(SNRindB4(i),Lc,A4,w0);
echo off;
end;
echo on;
Subscript indices must either be real positive integers or logicals.
Error in ==> F:\work\Untitled10.m
On line 9 ==> for i=1:length(SNRindB),

Answer 1

for i=1:length(SNRindB),多一个","是什么情况
