Confusing remark regarding "inhomogeneous systems of linear equations and affine subspaces" #738

Open herdem opened 1 year ago

Describe the mistake Notation is confusing. A@ Lambda=x is used to describe the affine space but in the paragraph below, A@x=b is used. Also the equation defining the hyperplane should simply be a dot product equated to a real (non_negative) number Location

  2. Chapter 2
  3. page 62
  4. Remark paragraph on the page

Proposed solution Rewrite the equation defining the hyperplane as a dot product equated to a real (non_negative) number : *Lambda.T@ x=b
