How do I display the terms of a binomial expansion (x+y)^n ?

I want to display the terms in terms of x and y i.e nCr x^(n-r) y^r with r going from 0 to n

One way,

n=4;
e=0:n;
C=arrayfun(@(i)nchoosek(n,i),e);

sprintf('%d*x^%d*y^%d  ',[C;e;n-e])

'1*x^0*y^4  4*x^1*y^3  6*x^2*y^2  4*x^3*y^1  1*x^4*y^0  '

I want to find the terms in the form : nCr x^(n-r) y^r

like if n==5;

I should get

x^5 5*x^4*y 10*x^3*y^2 10*x^2*y^3 5*x^1*y^4 y^5

[Anomitra Saha]

Can you tell me how to do this using for loop ?

[Matt J]

Just call sprintf() differently

sprintf('%d*x^%d*y^%d  ',[C;e;n-e])

'1*x^0*y^4  4*x^1*y^3  6*x^2*y^2  4*x^3*y^1  1*x^4*y^0  '
