timer object indicator
Hello to everyone, I need to contruct a timer object with a time delay or an indicator: Main program (slave computer) svrsock = mslisten(3000); % listening to the Master through a socket sock=msaccept(svrsock); msclose(svrsock); s=makesdata; The data s hava a particular structure. tpanel = ... 7 Jul 2010 09:02

Accessing Level 2 M File S Function Dialog Parameters
Hi All, I'm trying to generate code for a simple model which has a Level-2 M-File S-Function in it. My S-Function takes in one parameter from the dialog box which is used for some computation. I understand that I have to write a corresponding .tlc file to tell RTW how to generate code for this S-Function. My questi... 8 Jul 2010 01:33

Matrix returned as NaN
I am using a code that is used for optimal interpolation. My goal is to interpolate sediment diameters using this code. The test data the code comes with works fine however when I use my data it does not. Now the difference between the data that comes with is a average from the past being interpolated with new obser... 7 Jul 2010 10:08

So has anyone figured out a way to generate multi input NARX models I am stuck even though it seems that by the usual way one can combine the vectors into the input vector not sure how to enter delays(for multiple inputs) have tried all combinations but none seem to work even the system identification toolbox uses th... 7 Jul 2010 07:57

Simulink time innacuracy
Hi, I am using simulink to control a device via RS232. I can successfully communicate with it using the "To Instrument" block although for some reason the time scale is completely incorrect, leading to some strange responses. For some reason the simulation time seems to increment about 120 seconds for every real wo... 7 Jul 2010 23:23

Stacked bar
Is there any way to change the colors in a bar or two of the stacked bar graph without affecting the rest of the bars, in example; I have the matrix a where a= a= [1 2 5 3; 2 3 6 1; 3 5 6 4]; and I would like to plot is as stacked bar, so bar(a,'stack'); which creates 3 bars having 4 colored bits in each (dark blu... 8 Jul 2010 15:51

gene ontology enrichment analysis
Hi, I have 2 questions about geneontologydemo.m : 1. I am having a hard time understanding how the p-values are computed. In the demo: pvalues=hygepdf(upgenesCount,max(chipgenesCount),... max(upgenesCount),chipgenesCount); This is weird to me. Shouldn't it be: pvalues=1-hygecdf... 7 Jul 2010 07:57
