ENGIN 7 Study Guide - Midterm Guide: Interpolation, The Roots, Spline Interpolation
Document Summary
Your e77 lecture section 1(12-1pm) or 2(1-2pm) (circle your section #) Circle your lab section (where the graded midterms will be returned). Part i questions 1-5: systems of linear equations. Questions 1-5 refer to the following system of equations: 1. ( 1 point ) write the matrices so that this system of equations in the form ax = b. 2. (1 point) after correctly assigning the matrices a and b in matlab, to solve this system of equations via gaussian elimination we should type at the command prompt: >> a\b, >> pinv(a)*b, >> inv(a)*b, >> a"\b. 4. (1 point) consider the equations 2x + 4y = 5 and 2x + 4y = 7. The rank([2 4 5;2 4 7]) will be: 0, 1, 2, 3. 5. (1 point) consider the equations 2x + 4y + 3z = 5, 2x + 4y + z = 5.
