optimization of fiber bragg grating using nelder-mead simplex
i actually dont really understand about the objective function bcoz there is a lots of equation. so which one should i choose or how should i create an objective function. You might want to use some built-in MATLAB functions. fminsearch performs the Nelder-Mead simplex algorithm. It accepts a single vector... 6 Apr 2010 16:26

Remapping Matrix Values (3d to 2d) for Convolution
This is my first post... and I'm hoping I am overlooking something, but thank you in advance for any help. I am starting off with a 3d matrix of points that are values in space, a simulated volume. Each point is indexed with x, y and z values, e.g. Value = Matrix(xval,yval,zval). I have also calculated the r, thet... 4 Apr 2010 12:36

optimization of fiber bragg grating using nelder-mead simplexalgoritm
You might want to use some built-in MATLAB functions. fminsearch performs the Nelder-Mead simplex algorithm. It accepts a single vector of inputs, say x = [x(1),x(2),x(3)], and works on your objective function that should take x and return f(x), where f(x) is the function to minimize. For your problem, take x = ... 4 Apr 2010 12:36

need to interface PLC with Matlab
I'm also dealing with the same issue. From the researches I've made, I can see that there are 2 ways to communicate matlab and plc. one of them is the opc toolbox in matlab and the otherone is another software by a company you can search it as M2PLC however, since i am a beginner in matlab I couldn't solve my probl... 20 Apr 2010 15:55

Resetting for loop
I have a matrix with points and I have a for loop that will go through each of these points and if a condition is met it will delete one of the points from the list. But I want to reset the loop once it has deleted a few points as I get an error once my incrementing variable get too high for my formula. I have it so... 4 Apr 2010 23:39
