#!F-adobe-helvetica-medium-r-normal--18* #!N #!N #!Rtall525 Vectors #!N #!N #!N A vector is a quantity that has both magnitude and direction in #!F-adobe-times-medium-i-normal--18* n #!EF -dimensional space. It corresponds to a directed line segment whose length represents the magnitude of the vector and whose orientation corresponds to its direction. #!N #!N Vectors are composed of a sequence of scalar values enclosed by square brackets #!F-adobe-times-bold-r-normal--18* [ ] #!EF . The scalar values can be separated by commas if desired, although this is not necessary. If the elements of a vector are not homogeneous, (e.g., if they are both integer and floating-point elements), then the integer elements are converted to floating point. The following are all valid vectors: #!N #!N #!CForestGreen #!N #!F-adobe-courier-bold-r-normal--18* #!N [0.0 0.0 0.0] // the origin of a 3-D space #!N [0, 0, 1] // an axis in a 3-D coordinate system #!N [1, 1.0 1, 1.0 1] // a vector in a 5-D space #!EF #!N #!N #!EC #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ltall527,dxall527 h Matrices #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
