41. Let " X " and " Y " be column vectors of factor loadings for two different samples. 42. So, instead of viewing the data as an array of rows, they are seen as an array of column vectors . 43. The convention is to use column vectors and ( therefore ) multiply with the matrix on the left and the vector on the right. 44. In an-dimensional Hilbert space, } } can be written as an column vector , and then is an matrix with complex entries. 45. The natural bias to read left-to-right, as subsequent transformations are applied in linear algebra, stands against column vector inputs. 46. The right hand side is, which is applied to the column vector "'b "'of the right hand sides. 47. The cross product of any two column vectors is normal to that plane, and is an Eigenvector of A for \ lambda _ i. 48. If a is a row vector of size [ 1 n ] and b is a corresponding column vector of size [ n 1 ]. 49. As a matrix algebra, therefore, it acts on 2 " k "-dimensional column vectors ( with complex entries ). 50. And in turn, are column vectors ( the matrix transpose of these are row vectors ), and is the Lorentz factor of velocity.
