A/D Quantization error- reconciling
I am trying to simulate and understand the Signal to Quantization Noise Ratio (SQNR) for a linear ADC. This file will later be expanded to include noise shaping etc and also to choose the converter of choice. Here is my question- 1) I have calculated the Noise power using the variance of a uniform pdf which is ... 27 Jul 2010 16:09

newff error while calling a defined Matlab function from Java code
Hi! I'm new to Matlab. I'm using Matlab R2007a and Java. I defined a function using newff. I built java class file for that function using Matlab Java Builder. The function runs correctly from Matlab command line. But when I use it Java code it generates below error message and throws an exception. Why I'm getting ... 28 Jul 2010 15:09

rescaling for fmincon
I am running a least squares minimization with fmincon to solve a least squares problem. Essentially, a 5-tuple of parameters maps to an 8-tuple of percentages. The parameters are of the form (mean, 1/variance1, 1/variance2, 1/variance3, constant scaled to mean). Unfortunately, it seems that the sum of squares funct... 27 Jul 2010 16:09

Delete variable in multiple structures
Hi, I Have a main structure called "Results". In that structure, I have other structures that each contain different series. The series in each structure have the same name. For example, let say I have an exchange rate time serie from t=1 to T that is called S1. This serie finds itself in Results.Trend.S1. I als... 27 Jul 2010 16:09

How can I compute the probability that a set has normal distributionwith zero mean
Oleg wrote: I have two data tables as a result of two similar experiments. I want to check and, if possibly, to compare the chances whether residuals in rows have normal distribution with zero mean. The problem is that kstest compares with standart normal distribution (fixed mean and SD), and lilliet... 28 Jul 2010 10:45

How to display results into a test file or notepad
I created a listbox the played a series of random sound+noise.wav files. When a file was played it would ask me the patient got the response correct or not. It will continue asking me until I have hit 14 reversals (switching from yes to no responses). It displays the final db threshold of the SNR. Now I need help in pr... 28 Jul 2010 11:51

How can I compute the probability that a set has normal distribution with zero mean
I have two data tables as a result of two similar experiments. I want to check and, if possibly, to compare the chances whether residuals in rows have normal distribution with zero mean. The problem is that kstest compares with standart normal distribution (fixed mean and SD), and lillietest is nonparametric test. Th... 30 Jul 2010 05:20

load error
I have two folders (conf1 and conf2). In these two folders I have the same variables. I pretend to use the load command however I am not being able to do that. This is the part of the code that I have created: n_g=2; path = pwd; for i =1 : n_g load([path num2str(i) '.mat']); end Could anyone please give me a... 28 Jul 2010 10:45

Distribute Matlab figures
Hi, I produced a number of Matlab figures (*.fig). How can I distribute these figures to other persons who don't have Matlab installed in their computers? Those are 3D plot so that they could also rotate the figures freely. Thanks. ... 27 Jul 2010 16:09
