Abstract
The Schur complement is used to invert a matrix that is otherwise too large to invert on a personal computer. The implementation of this program relies heavily on the usage of files. Although the file I/O (input/output) increases the time of inverting these matrices, this does not lessen the value of this method since it will invert matrices that are too large to reside in the memory. This method hinges on blocking the matrix M and using the Schur complement to invert the blocked matrix
