MATLAB: How can I create a series of same length vectors, extract from each the maximum number, and collect the maximum numbers in a new vector

Question

if true
b=5;
muH=b*sqrt(pi/2);
n=100000; % n different vectors
H= rand(1,1000); 
h=(muH/mean(H))* H;  %vector  
max=zeros(1,n);
for k=1:n  %it creates n different vectors each containing 1000 numbers 
max=max(h(k)); %extract maximum from each n vectors 
end
end

Answer 1

clc; clear all ;
b=5;
muH=b*sqrt(pi/2);
n=100000; % n different vectors
iwant=zeros(1,n);
for k=1:n  %it creates n different vectors each containing 1000 numbers 
    H= rand(1,1000); 
    h=(muH/mean(H))* H;  %vector  
    iwant(k)=max(h); %extract maximum from each n vectors 
end
