    can you make this video louder. it wasn't loud enough

  • @kotosif
    @kotosif Před 7 lety +2

    Am I right in saying that if you compute the range this way, the spanning set is also equal to the basis of the matrix?

    • @joyzhou4917
      @joyzhou4917  Před 7 lety +4

      First of all, there are more than one spanning set for the range of the matrix. There are also more than one basis for the range of the matrix. If a spanning set of the range is linearly independent, then it is a basis for the range. I would not make "spanning set" an equivalent concept with "basis" no matter what method you use.

    why is the 1 on the last column not consider a leading one?

    • @frankbesson4814
      @frankbesson4814 Před 7 lety +2

      It has to be the first digit in a row to be considered a "leading one".

    • @joyzhou4917
      @joyzhou4917  Před 7 lety +5

      Reducing a matrix to row echelon form? In fact, in the video I reduced the matrix to its reduced row echelon form (RREF).
