Here is my code. How can I reduce that time without changing the result?
clear all;clc;close all;
L=1000;
c = randn(1,1000000);
cont3 = 1;
while cont3 < length(c)+1
if(abs(c(cont3)) < 1 || abs(c(cont3)) > 10)
c(cont3) = randn(1);
cont3 = 0;
end
cont3 = cont3+1;
end
c;

You can operate on the entire vector using for example
a(a<1) = randn
So you could make a loop something like
while any(a<1) || any(a>10)
a(a<1) = randn(sum(a<1),1)
a(a>10) = randn(sum(a>10),1)
end

Sorry I didn't look at your specification carefully. Anyhow you should be able to modify
while any(abs(a)<1) || any(abs(a)>10)
condition1 = abs(a) < 1;
a(condition1) = randn(sum(condition1),1);
condition2 = abs(a) > 10;
a(condition2) = randn(sum(condition2),1);
end
