Hi everyone, is it possible to build an interface link between matlab and STK codes? I explain : part the output from STK are given to matlab code. It elaborates them and gives a feed-back to STK that continues its iteration. It's an iterative process. Is available a program like that? Any idea? Thanks in advance, Lupin
Hi, I'm simulatin a lecture in FIR filter desigening I'm to desigen the filter (not using filters in matlab) the desigen scheme is iterative in witch each iteration requires 2 FFT computations. any way, I need an initial estimate & the lecture uses the ideal filter (LP)(rectangular) . I use the fir2... function in order to compute the
Hello, My work is on numerical techniques which require to solve sparse matrices etc. All my work is in fortran and I have almost no skill in matlab.But I have just realized that matlab can do some computations quite easily with its built-in functions and I want to take advantage of this. I have no time to learn matlab deeply or work on (...)

hi, i'm facing a problem with this attached matlab file. i don't know what this problem is but all what i know that the system is giving me zero output. when i tried to redo it by minimizing the no. of components that i put a hydraulic source with the pressure sensor but it said "Trouble solving algebraic equations in differential-algebraic system
Hi I am doing a turbo codec using matlab. I finished the encoding part and stuck up with the decoder. I tried using 'vitdec' a ready function available in matlab, but i cannot get soft outputs so that i can pass that info to the second decoder and begin the iteration process
Hi Try sim() function of matlab to execute your model in each iteration of loop. Like fid=fopen('file.txt'); fseek(fid,94,'bof') n=0; for (n=0:6) pause(0.5); A = fgetl(fid) A=str2num(A) sim('your_model'); % Collect output here. end fclose(fid);
hey all, i have a matlab code that i should run it in (from 2 to 9 minutes) but it runs in 45 minutes, so i have ideas about improvement the performance of the code by minimize the loops and the use of pre-allocations of vectors, but still run in 45 minutes, any other ideas or advices for the improvement of the code ( outer loop iteration=15..inner
A declaration like that defines the variable as a) existing, and b) being empty. (Disappointingly, the following lame example of bad programming practice is the best that springs to mind :) Let's say you have a loop in which a variable dynamically grows with each iteration*. For example: for i=1:10 a = ; end (This will build a row vec
Wow, buddy Square root should be avoided in matlab? Is this your suggestion for all the equations? or only this one? When solving something for numerical methods you have to be careful with the function domain, because if an iteration falls outside (eg. complex values in real function, division by zero or ne
Hi everybody, I got a problem when I try to use matlab connecting with CST 2010 and applying GA for simulation antenna. I setup for maximum of iterations (maxit) 100. But my simulation always stopped at the iteration of 26th. And a message appeared as "Server threw an exception". matlab can not call CST to keep run (...)
Dear all, I want to know as how to store iterated result in matlab. I'm using a for loop,for every iteration of for loop i want to store the output.After completion of all iterations, the outputs are to be added for final result. In C language we use array.But in matlab, i'm not sure as how to code it. Plz (...)
Hi Joserse, I've not examined in detail the code (the lack of indentation make it a bit more difficult to identify loops and nesting), but these are some hints: = Move out the loops calculations that wuold be repeated at each iteration. For instance, sqrt(EB_NO*2) is used a lot of times inside loops, requiring the calculation of a square
Can anyone please tell me what I need to do to enable me make MAPLAB plot the following outputs against time i.e. 1. Here I am differentiating the system step response, to show that this give the impulse response, but how do I make matlab do ?plot(t,x)? where t is 0 to 8ms and x is the step response differentiated. clear num=[0 0 20210
I am running SuperNEC with matlab 6.1. When I create a structure expecially a more complex one like a cone or a parabola, it takes a very long time to make the structure. It almost takes longer than to run the simulation. Has anybody else experienced this as well? Is this normal?

Hi "matlab 5 User contributed M-Files" 1. -> t tnx
i have to make this 2 programs, if anyone could help me out, i would apreciate it: 1- Write a matlab program to compute the first L samples of the inverse of a rational z-transform where the value of L is provided by the user through the command input. Using this program, compute and plot the first 50 samples of of the inverse of G(z) from Eq. 3.3

Dear friends: Is it possible to use matlab code (or code translation) in a development under Delphi or Visual basic?. How can do it , what's the better way? I understand that matlab provides a compiler to C, C++ code, but how can I link this code with a delphi application? Thanks great peopple Nebisman
