RS232 problem
Hi. I am trying to read data from a laser sensor and send G_Code to a CNC at the sane time. I used Real Time Windows Target for reading data, and used an m-file to create an RS232 object. This m-file leads both operations. It worked perfectly for a bout 20 line of G-Code and then the CNC stop giving an alarm of ... 27 Jan 2010 23:54

ARMA model fitting
Hi, I've been working in developing input/output ARMA model for surface roughness profile. I am using MATLAB armax command for that, which has a flexibility to choose my model's order. I was just wondering, is there any way I can plot the residuals, obtained from the ARMA model. My intension is to verify the adequacy ... 2 Feb 2010 21:59

m-file function to find inverse matrix
1)Write an m-file which finds the inverse of an nxn matrix by Gauss Jordan elimination. 2)Write an m-file which finds an orthogonal matrix P that diagonalize an mxn matrix A. Then, find the diagonal matrix D, i.e., D=PT AP. Hint: Apply three steps in Chapter 7.3. To find bases of an eigenspace of a matrix, use... 27 Jan 2010 23:54

reshuffle different parts within a sinus to construct a new one
Dear all: I have some human performed sinusoid signals and would like to reshuffle all parts within a sinus so as to construct a new sinus with same characteristics at least in the amplitude and frequency domains. For example, a sinus has a frequency from 0.6 to 1 Hz and amplitude from 2 to 8. Could anybody help me ... 2 Feb 2010 15:17

world magnetic model 2010
Hi, Matlab has a function called wrldmagm which returns the earth's magnetic field at a given time and coordinate. This uses the World Magnetic Model which is updated every five years - so if you are looking for a date in 2003, for example, you need to tell wrldmagm to use the year 2000 file, and after 2005 the yea... 23 Mar 2010 07:50

Genetic programming and MATLAB scripts
Hi, I'm experimenting with variants of genetic programming. I have built a routine that reads a set of variables and based on their value constructs an .M script file. I did this with the intention of running this dynamic .M file as a changing function that I could execute as I was iterating in the algorithm. Ho... 27 Jan 2010 19:27

GUI with impoint
G'day everyone, this is my first post to this forum though it has already helped me many times in the past. I am developing my first GUI using GUIDE, it essentially opens a set of 2D data maps and displays them whilst plotting some data taken from them. I have generated an impoint so that the user is able to select ... 13 Feb 2010 16:02
