                                    Linear dependence and independence of vectors
     •  In this topic, we will Introduction
         – Define linear dependence and independence of a given vector v
            on a collection of vectors
         – Determine how to check if a vector linearly depends on others
         – Define the rank of a matrix
         – Define a linearly dependent collection of vectors,
               and a linearly independent collection of vectors
         – Determine how to check if a collection of vectors is linearly 
            dependent or independent
         – Consider a few results
                                                                        2
                                   Linear dependence and independence of vectors
                                Definition
     •  A vector u is said to be linearly dependent on a collection of
        nvectors v1, …, vn if u can be written as a linear combination
        of the vectors v , …, v
                        1      n
         – That is, u is linearly dependent on v1, …, vn if the problem
                              v +    +    v =u
                               11          nn
            has at least one solution
     •  If u is not linearly dependent on a collection of
        nvectors v1, …, vn, we say u is linearly independent of v1, …, vn
         – That is, the problem
                             v +     +    v =u
            has no solutions   11          nn
                                                                       3
                                 Linear dependence and independence of vectors
                          The zero vector
     •  Note that the vector 0m is linearly dependent on any collection of 
        nm-dimensionalvectors as 
                           v +    +   v =0
                            11         n n    m
        always has at least one solution: 
                            =     =    =0
                             1         n
                                                                 4
