C program for partial pivoting

C Program for LU Factorization. C Program for Regula Falsi Method. C Program for Newton Divided Difference. If available. Can you also include the function of partial pivoting in this program? What do you mean by some special matrices?

When using floating point arithmetic, there can be pitfalls to this method. The equations are not scaled, but scaled values are used to determine the best partial pivoting possible. Matrices are allocated in such a way so that the index starts from 1, not from zero. So the first element of a matrix A is A[1][1], not A[0][0]. The co-efficient matrix must be a square one. The constant matrix has been implemented as a column. Although it could have been implemented as an n x 1 matrix, I chose not to.

I have tried to apply the same implementation on Matrix generated based on Finite Field I made sure that I have changed all the operations of add, sub, div and mul to be FF operations.. However I did not get and Identity Matrix in the end? Can you please help me.

Improve this answer. Of course, I thought about one of the elements on diagonal to be 0, but didn't thought they could be 0 after the operations done to convert the matrix to an superior triangular one. I think I found the other problem too. I'm searching for the max element on the whole column, not only below the pivot. Sign up or log in Sign up using Google. Sign up using Facebook.
