"Vector" is not considered a > part of "linear Algebra", it is a part of Physics and Calculus. So unless you > have an 8th grade education and that is where you stopped, your definition of Linear algebra from 8th grade is different from the college level linear algebra - it generally deals with the specific case of two dimensional space. A college linear algebra course will deal with Ax = b in n dimensional space. A is a matrix, and x and b are called vectors, which are really (at least in this context) simply a n x 1 matrices. (Note that in matrices mxn means m rows and n columns reverse of normal x, y convention) -- /*************************************************************\ **< jrmorris@macalstr.edu >*< cuth@gryphon.ccs.brandeis.edu >** *************************************************************** **< Jesse Morris >************< enrico@max.tiac.net >** **< Macalester College >************************************* **< 1600 Grand Avenue >*** Fencing - Juggling - Madness ** **< St. Paul, MN 55105 >**** C Programming - Musicmaking *** **< voice 1.612.696.7284 >*** Dramatic Lighting - Et cetera ** \*************************************************************/
