A method for calculating interval inverse matrix

This paper has presented a method for calculation the interval inverse matrix using the linear equation system. Linear equation systems have important in mathematics, engineering, statistics and other disciplines. These systems can vary in the interval are searcher who have been considered. Also whit this type of systems have been encountered in many applications. Different bases of interval calculation has been discussed in several articles [2,5,6,7]. The method used in calculation in inverse matrix real case, we can extend it to the interval mode. To calculate the interval inverse matrix we define many definition that are consist of interval one number, interval zero number and interval identity matrix. It is noted that the uniqueness of the calculated interval inverse matrix is not guaranteed.
