please explain the following loop with each line working details

C=d(n,n);

fork=n-1:-1:1

C=conv(C,poly(x(k)));

m=length(C);

C(m)=C(m)+d(k,k);

end

here ,d is an array varibale

The origin of the code seems to be

https://www3.nd.edu/~zxu2/acms40390hw/newpoly.m

% NUMERICAL METHODS: MATLAB Programs, (c) John H. Mathews 1995
% To accompany the text:
% NUMERICAL METHODS for Mathematics, Science and Engineering, 2nd Ed, 1992
% Prentice Hall, Englewood Cliffs, New Jersey, 07632, U.S.A.
% Prentice Hall, Inc.; USA, Canada, Mexico ISBN 0-13-624990-6
% Prentice Hall, International Editions:   ISBN 0-13-625047-5

And the topic is explored a little at

http://boron.physics.metu.edu.tr/NumericalComputations/Fall2004/week6l/week6l.pdf

It has to do with Newton Interpolating polynomials.

At the moment I do not understand how the code works, but I would expect that the Numerical Methods text would go into it further.

Please tell.me following statement's details C=conv(C,poly(x(k)))
