This page allows to find the determinant of a matrix using row reduction, expansion by minors, or Leibniz formula. Questionnaire. Note: A randomization method is used to avoid cycling. For a square matrix the determinant can help: a non-zero determinant tells us that all rows (or columns) are linearly independent, so it is "full rank" and its rank equals the number of rows. Set the matrix (must be square) and append the identity matrix of the same dimension to it. Genetic Algorithms Stock Portfolio Generator, Scan for all machines running IIS in a domain, Extract data from a Microsoft Word document, lecture 7 on Linear Algebra by Professor Gilbert Strang (available at MIT OpenCourseWare), Problems, Comments, Suggestions?
