Same problem, but page breaks. I apologize for this:

Repeatedly multiply the matrix R -[cos(pi/4) sin(pi/4); -sin(pi/4) cos(pi/4)] by the column vector el0and draw a conclusion about what the matrix R is doing to the vector. Tip: Try drawing the vectors el, Rel, R'el and so on. For several, try the following code after you have defined el and R. x-el 3311 EHW 2 Page 5 of for i 1:8 x-(x RM4e1; end % use the semicolon to surpress a lot of output %(Highlight these last three lines of code and run together.) % Just what are the columns of x? plotv(x) Repeatedly multiply the matrix R -[cos(pi/4) sin(pi/4); -sin(pi/4) cos(pi/4)] by the column vector el0and draw a conclusion about what the matrix R is doing to the vector.
