WebMultiplying matrices is useful in lots of engineering applications, but the one that comes to my mind is in computer graphics. You can think of a point in three dimensional space as a 1 by 3 matrix, where the x coordinate is the 1,1 value in the matrix, y is the 1,2 and the z coordinate is the 1,3 value. Like this: [x y z] WebRectangular coordinates specify a position in space in a given coordinate system as an ordered 3-tuple of real numbers, ( x, y, z ), with respect to the origin (0,0,0). Considerations for choosing the origin are discussed in Global and Local Coordinate Systems. You can view the 3-tuple as a point in space, or equivalently as a vector in three ...
