formulating matries based on polynomials entries.

[sheff]

HI Everybody,

I have got a polynomial S= [ 1 2 3 4 ];

I want to write this in a matrix form so it goes,

S= [ 1 0 0 0 ]
[ 2 1 0 0 ]
[ 3 2 1 0 ]
[ 4 3 2 1 ]

Any ideas of hwo this can be done in USING C PROG LANG???

Use an array with 2 indexes

int S[4][4];

See Arrays Revealed for more information on multi-indexed arrays.

HI Banfa, thnx for ur reply, the polynomial S= [ 1 2 3 4 ]must be formulated to the new S that is in the form of a matrix using some opertation, it will be part of code and the dimenation of the polynominal will vary each time , any ideas?
