"axis xy" vs. "imwrite"
This time I want to write an image I need to display with "axis xy" instead of "axis ij" to disk using "imwrite" - without having it flipped or mirrored in any way. I certainly do know that MATLAB follows a quite comfortable convention of having an image's origin in the upper left corner, but in my case I have a geo... 26 Mar 2010 06:53

designing of high temperature superconducting power cable using matlab
As a part of my project I want to design mat lab blocks for High temperature superconducting(hts) power cables which are used in transmission lines,this is an advanced technology and also it may be possible for designing both for ac and dc transmission.If not possible please provide me some contact information of mat l... 26 Mar 2010 04:41

Plotting piecewise function
I am having great difficulty with trying to plot a piecewise function. I am not allowed to use piecewise_eval etc but rather with a control loop etc. I have already spend one week playing around with for loop, while loop, if elseif etc but I am still getting error.Can someone please help me? The problem is this. Plot x... 29 Mar 2010 11:20

load, use and save again the data
Hi all, I am completely over because of my GUi, I prepared a Gui for my thesis which includes several evaulation. First, it starts with load (*.grd) data and after the function save it (.mat) data. But I didnt solve how can I call the file again for the later applications in the same gui with no changing in coding (fi... 27 Mar 2010 09:34

Reading subset from text file
Dear all, I have text file with 500k columns and 4 rows. At one time I need for processing only data from 1:10k points (from all 4 rows), next time I need points from 10001 to 20k and so on. Because to minimize memory requirements, i don't want read all data from the file at one time, but I don't know how to read se... 26 Mar 2010 02:30

maximization using fmincon
I have problem in maximizing a simple quadratic function (by minimizing the negative of the function) subjected to an inequality constraint using FMINCON. The solution provided by fmincon is an unconstrained solution. Why does fmincon disregard the inequality constraint? Here is the code: Q = eye(2) ; A_ineq... 27 Mar 2010 19:56

Neutral wire and Simpower Synchronous Machine
Is it possible to have a 4-wire synchronous machine with the simpower toolbox ? I've only seen the simple model which proposes it, but this model does not meet my requirements (I need d-q values and saturation). I'll need the neutral wire to connect the generator to a 3 diode rectifier; If you have an other idea to ... 26 Mar 2010 00:18

how to check intersections between 2 3D objects?
Hi Anyone know how to check 2 3D objects intersect with each other? For example, how to check to whether 2 cylinders join with each other? In 2D, function inpolygon can be used to check whether a point is inside a polygon or not, is there any similar function can be used in 3D case? Thanks! DZ ... 26 Mar 2010 00:18
