... BUT - it turns out you can use either notation in Matlab! First try the inverse style: x = inv(A)*b Now try the division style. It’s a little different from what you would expect: x2 = A\b Notice that the A comes first, and that the slash is a back-slash. This basically tells Matlab “Solve Ax = b fo ...

... III. Gaussian Elimination with Back-Substitution This last matrix is in row-echelon form. Here are the characteristics that define a matrix to be in row-echelon form: 1. All rows consisting entirely of zeros occur at the bottom of the matrix. 2. The first nonzero element of any row is 1, called a ...

... We skipped the example below and the equations of a plane. Equations of planes. a(x − x0 ) + b(y − y0 ) + c(z − z0 ) = 0, where (x0 , y0 , z0 ) is a point in the plane and n = (a, b, c) is normal to the plane. In fact, if (x, y, z) is a point in the plane then the vector (x − x0 , y − y0 , z − z0 ) ...

... (3) In the case of a symmetric matrix, the n different eigenvectors will not necessarily all correspond to different eigenvalues, so they may not automatically be orthogonal to each other. However (if the entries in A are all real numbers, as is always the case in this course), it’s always possible ...

... 4. Another approach is to define, instead of the above two functions, the single function Y1 = 2 cos x – x – 1, and then find its roots. Approximate roots may be found by tracing and zooming, and it is easy to see that the equation has three solutions. On the CALC menu, roots are found using . Use t ...
