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

Note that numeric arrays should be preallocated before the loop, e.g.:
M = nan(1,n);
for k=1:n
M(k) = ...
end
See: https://www.mathworks.com/help/matlab/matlab_prog/preallocating-arrays.html
