Basically, I'm supposed to write my name using splines in Matlab. Now, I'm having some trouble getting a parametric spline to work and I can't for the life of me figure out the problem. I'm making use of the spline toolbox and I have written a script as so:
%segment for the S
x1 = [0 2 1 2...
Thanks frederick, that definitely helps a lot. Let me make sure I understand:
If A = [2 0 0; 1 5 4; 1 2 4] (arranged by column) then my determinant is simply 2 * 5 * 4?
Yea there will be no decimal values as there is no calculator on the midterm. Also, once I find the 3x3 matrix I end up having to solve a cubic (in most cases) which also takes time. Is there no easier way to get the eigenvalues of a 3x3 (with whole numbers eigenvalues) rather then just...
I have a midterm tomorrow and I find I'm quite slow at finding the determinant of a 3x3 matrix. Basically I'll only need to find the determinant to find the characteristic polynomial (at least for this class) and my prof on the board does it so fast, I'm wondering if there's some trick I missed...
