PPT-Introduction to Vectors and Matrices

Matrices Definition A matrix is a rectangular array of numbers or symbolic elements In many applications the rows of a matrix will represent individuals cases people items plants animals and columns will represent attributes or characteristics. In particular they are useful for compactly representing and discussing the linear programming problem Maximize subject to i j This appendix reviews several properties of vectors and matrices that are especially relevant to this problem We shoul Such matrices has several attractive properties they support algorithms with low computational complexity and make it easy to perform in cremental updates to signals We discuss applications to several areas including compressive sensing data stream Nickolay. .

A . . is a rectangular arrangement of numbers in rows and columns. . Matrix A below has two rows and three columns. The . . of matrix A are 2X3 (two by three; rows then columns). The numbers in the matrix are called . vectors and matrices. A vector is a bunch of numbers. A matrix is a bunch of vectors. A vector in space. In space, a vector can be shown as an arrow. starting point is the origin. ending point are the values of the vector. Matrix Multiplication. Matrix multiplication is defined differently than matrix addition. The matrices need not be of the same dimension. Multiplication of the elements will involve both multiplication and addition.
