Get function of variable
Dear I want to make a function of a variable, I have a string variable with an equation in it and I want to construct a function which I can use for lsqcurvefit. I have this: % x0 are my initial parameters % ind is a column matrix with x and y values in it equation = x0(1)*ind(:,1).^x0(2)+x0(3)*ind(:,2).^x0(... 17 May 2010 11:18

spdiags()
I'm working on the direct solution of the discrete ordinates, a common technique in radiation transport. Without going into details, I create a set of diagonal vectors for constructing a sparse matrix K to solve Kx=b. The lower and upper diagonals are stored in kL and kU, while the center diagonal is kC. I construct... 16 May 2010 14:38

Plot line between two points on ellipsoid
I have two points on the surface of my ellipsoid. I calculated the distance between them with the Vincenty formula. But now I want to plot this distance on the ellipsoid distance as a line as well. For a sphere this is easy, but I do not know how to do it for an ellipsoid. ... 17 May 2010 05:51

How does Matlab "sum" function works?
I tried performing summation of an array, A, using two ways: 1) sum(A) 2)x=0; for i=1:n %n is the size of the array x=x+A(i); end x %x is the sum I found that method 1 is significantly faster, especially when the array size is large. At size of 1048576 the first method yields result in 0.0035 s whereas t... 17 May 2010 06:56

Display Video of Simulink in GUI
I think that Danh has the same problem with me if I understood well. Well actually Simulink opens a new window every time that displays a video. All I want is to embed this video in a Gui that I have already made with Guide for changing the parameters of my Simulink model. How can I send the video to the Matlab GUI. I ... 16 May 2010 11:20
