That's exactly what the problem said. I believe it means that the line is contracted by a factor of 3 only and the points are dilated by 3. What I had thought was that I was supposed to pick 2 points from W and then use the span as the third point. And then like you did set [L]en = xnvn...

Homework Statement L:R3->R3 is a dialiation by a factor of 3 of points in the plane W given by the equation z = 0 and a contraction along the line L = span({(1,0,0)}) by a factor of 3. Find [L], but I'm mainly concerned with finding L(e31) Homework Equations z = 0 L(1,0,0) =...

Thank you, I did and everything checks out.

So what I calculated: L(0,3) = (0,3) L(4,0) = (4,8) L(4,3) = (4,11) L(2,5) = (2,9) L= ((a,c)|(b,d)) For the first point: ((a,c)|(b,d))(0,3) = (3b,3d) 3b= 0 -> b=0 3d = 3 -> d=1 Second point: ((a,c)|(b,d))(4,0) = (4a,4c) 4a = 4 -> a=1 4c = 8 -> c=2 So L = ((1,2)|(0,1))

Homework Statement Homework Equations L(x,y) = L(x+y,x-y) L(x,y) = L(x) + L(y) L(kx) = kL(x) The Attempt at a Solution I'm very confused on this. I've look all over and haven't figured this out yet. I'm there's one simple piece of info I'm missing and then it'll all make sense, but for the...

what he said.

The identity matrix is actually 4x4: [1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1]

Homework Statement Given p(x) = x4+2x2+1 and A = [[1 1 -2 0] [0 1 0 2] [1 1 -1 1] [0 0 -2 -1]] p(A) = 0 Find a polynomial q(x) so that q(A) = A-1 a) What is q(x)? b) Compute q(A) = A-1 Homework Equations I found the Cayley-Hamilton theorem, which states: p(x) = det(A-xIn)...

Thank you for the explanation lanedance. I didn't know about symmetric matrices.

Homework Statement Examining the answers of the previous two questions, write the quadratic polynomial f(x1,x2,x3)=x1x2−6x22+3x2x3−3x23 in the form f(x1,x2,x3)=[x1x2x3]A[x1x2x3]<-this last group is a column matrix where A is a symmetric matrix. Homework Equations Matrix multiplication...

Got it working, finally. Lots of small errors that were kicking me in the butt. Appreciate the 3rd perspective and all the help. :)

Well the space is allocated like that because the program is supposed to be able to handle up to 32 integers (138/4 = 32) and set1 & set2 are half that (69*2 = 138) because I split the set in half.

Sorry, I use Notepad++ Also thought it would be easier to view it in notepad than on here, because it is long. I'm trying to work my way step by step with a set size of 2-4 elements to see what's happening. Will continue...

Ok one more time guys. I've compiled everything and it runs, but for output all I get are zeros. I'm not sure where my error is, I was hoping to get a fresh pair of eyes. :) The purpose of the program is to take an even number of user inputed integers and sort them (using merge sort). It...

Yes, I read through the list grep gave. Apparently I've been misusing registers lol. MIPS is a little different from what I'm used to.
