The idea behind those definitions is simple : every element can be written as a linear combination of the vi v i 's, which means w =λ1v1 + ⋯ +λnvn w = λ 1 v 1 + ⋯ + λ n v n for some λi λ i 's, if the vi v i 's span V V. If the vi v i 's are linearly independent, then this decomposition is unique, because.And we just showed that these guys are not linearly independent. So that means that they are not a basis for the column space of A. They do span the column space of A, by definition really. But they're not a basis. They need to be linearly independent for them to be a basis. So let's see if we can figure out what a basis for this column space ... 3. The term ''dimension'' can be used for a matrix to indicate the number of rows and columns, and in this case we say that a m × n m × n matrix has ''dimension'' m × n m × n. But, if we think to the set of m × n m × n matrices with entries in a field K K as a vector space over K K, than the matrices with exacly one 1 1 entry in different ...Here's a set of vectors: $\{ (1,0), (2, 0), (3, 0)\}$. According to your sentence, the dimension of this set is the number of vectors in the basis. That leads me to ask "What basis?" and "Even if you gave me a basis, what dimension would you say this particular set has? Notice that the set contains exactly 3 vectors." $\endgroup$ –in which case the matrix elements are the expansion coefficients, it is often more convenient to generate it from a basis formed by the Pauli matrices augmented by the unit matrix. Accordingly A2 is called the Pauli algebra.
