The rigidity of a matrix A for target rank r is the minimum number of entries of A that must be changed to ensure that the rank of the altered matrix is at most r.

In this paper, we discuss generalization of structure a set of specific rigidity matrices and some ideas that have been studied around in the Affine case.

Keywords: Elimination Theory, Projective space, Rigid Matrices.
