2:45.

**May 19. **Solutions to the May 18 problems are here.

**May 18 **As a way of reviewing the A6 material,
complete the following functions so that they perform as specified. (Solutions
at review session and posted tomorrow.)

function B = RevProb1(A,c,s,i,j) % A is n-by-n and 1 < = i <j <=n. % Let Q be the n-by-n matrix that is the identity everywhere except % Q(i,i) = Q(j,j) = c and Q(i,j) = -Q(j,i) = s. % B = Q'*A*Q function [B,C] = RevProb2(A,u,v,w,x) % A is n-by-n and u, v, w, and x are column n-by-1 vectors % Let M be the n--by-n matrix defined by M(:,j) = u(j)*w + v(j)*x % B = M*A and C = A*M function x = RevProb3(U,S,V,b) % U and V are n-by-n orthogonal matrices, S is a diagonal n--by-n % matrix, and b is a column n-vector. x solves (U*S*V')x = b.

**May 17 **Tentative A6 solution guide is available.

**May 14. **Here is a practice
final and an actual final from
previous years. Each has a differential equation problem which you can ignore.

**May 12 **

Final exam will be Friday, May 21, 9-11:30AM, in Ives 305. The exam will cover those concepts that are associated with A1-A6 and all the Section problems. A set of study problems will be vailable soon.

Review Session will be Tuesday, May 18, 7:30-9:00pm in Upson B-17
