Direct linkStuart, Jeffrey – International Journal of Mathematical Education in Science and Technology, 2010
Most students complete their first and only course in linear algebra with the understanding that a real, square matrix "A" has an inverse if and only if "rref"("A"), the reduced row echelon form of "A", is the identity matrix I[subscript n]. That is, if they apply elementary row operations via the Gauss-Jordan algorithm to the partitioned matrix…

Peer reviewedGivan, Betty; Karr, Rosemary – Mathematics and Computer Education, 1988
The author presents two examples of lattice multiplication followed by a computer algorithm to perform this multiplication. The algorithm is given in psuedocode but could easily be given in Pascal. (PK)
