abstract:In projective geometry, a collineation is a one-to-one and onto map (a bijection) from one projective space to another, or from a projective space to itself, such that the images of collinear points are themselves collinear. All projective linear transformations induce a collineation.
In this paper, by application of matrixelementary operation, we give the methodofsolving for planeprojective collineation. The method presented in this paper is simpler and clearer thanusedone.
