for i=1:n
    M=input('Enter array')
    
end

I see the result as,

M= 1 2 3

M= 3 2 4 and so on.

But i want to see that

M1= 1 2 3

M2= 3 2 4 and so on

How can i fixed it?

Better to go for M{1},M{2}.....as a cell array, here M{1}, M{2} are arrays having any size

M=cell(1,n)
for i=1:n
M{i}=....
end

if M1 and M2 are scalars then

M=[];
for i=1:n
M(i)=....
    end

More discussion on M1, M2 like variables, read here

Thanks for both of you

Note that numeric arrays should be preallocated before the loop, e.g.:

M = nan(1,n);
for k=1:n
   M(k) = ...
end
