1. The problem statement, all variables and given/known data If, in a matrix, there is a column of all zeros, does this mean the given vector/matrix is linearly dependent? An example would be: [1 2 0 4] [2 3 0 1] [5 2 0 7] A few questions to clear up some possible misconceptions: 1) The matrix above is a 4-dimensional vector? 2) The given vector has 4 unknowns, but a column of zeros, therefore the system is linearly dependent. Thanks for your help!!!
