The vector space Cm is the set of all column vectors (Definition CV) of size m withentries from the set of complex numbers, C.When a set similar to this is defined using only column vectors where all theentries are from the real numbers, it is written as Rm and is known as Euclideanm-space.The term vector is used in a variety of different ways. We have defined it asan ordered list written vertically. It could simply be an ordered list of numbers,and perhaps written as h2, 3, −1, 6i. Or it could be interpreted as a point in mdimensions, such as (3, 4, −2) representing a point in three dimensions relative to x,y and z axes. With an interpretation as a point, we can construct an arrow from theorigin to the point which is consistent with the notion that a vector has directionand magnitude.All of these ideas can be shown to be related and equivalent, so keep that in mindas you connect the ideas of this course with ideas from other disciplines. For now,we will stick with the idea that a vector is just a list of numbers, in some particularorder.
