precise numerical integration
Hello dear friends... I would to know if you know any other numerical integration method besides 'trapz' given x an y vectors: Area = trapz(x,y) my data are kind of randomic and I have obtained areas that are not so precise, numbers are not matching...So I was wondering if you could give some help on increasin... 4 Jun 2010 00:30

Elements of an Array in For Loop
Hello, How do you refer to the elements of an array that you load in a for loop? In the code below, for the subplot section how can the variable be set so that it changes every time from X1 to X2 and so on until the loop gets over. Thanks for your input! ~Mika % Data file containing coordinates to be plott... 3 Jun 2010 20:08

Pseudo Eigen-Decomp?
I'm well aware of eigs() for standard eigenvalue problems, but is there a function (or a way to use eigs() maybe?) to solve the following eigenvalue problem: A*x = c*conj(x) ? Here, A is a 2x2 matrix with complex entires, x is a 2x1 complex "pseudo eigen vector", and c is a constant eigenvalue. Note the only ... 10 Jun 2010 08:52
