that's exactly what i figured. thank you.

Thanks for the reply. I apologize that my question wasn't clear. I meant why are they choosing 80 samples?

Hi, I am pretty new to Matlab and am trying to reduce the noise of a particular signal. I found this pdf online and found it to be helpful. However, I am having trouble figuring out what the freq=(0:79)/(2*n*dt) means. More specifically the 0:79 bit. Any help would be much appreciated...

Thanks Stewart. Simply getting input on how odd this is reassures me that it's not my lack of experience that is preventing me from finding a solution...or at least cannot be blamed completely for it.

I wish I knew where all of these errors were coming from. There are actually two instruments that have identical designs but I only have had time to take a look at one. I am certain that looking at the second one will help identify, or at least clarify, some of the reasons behind the issues. And...

Hey Danger. What do you mean by weeding out inaccuracies? Could you explain a little bit more? Do you mean identifying them and then documenting them?

Hi all. I have recently taken on a project that involves a device that is instrumented with strain gauges (think of it as a cantilever tube with strain gauges at one end...the instrument details aren't too important for the question). Now, this instrument has SO many errors that I do not know...

I have collected and plotted thousands of data points and would like to now find where the center of this "data cloud" lies. I was wondering if anybody had an idea as to how I could approach this in Matlab. Thanks in advance.

I am simply trying to find a way to set the plot increments to a set value. So I want the increments to be increasing by 10's (10, 20, 30, etc) and I want the physical distance between them to be the same on all plots (I do not really care what distance they are but they just all have to be the...

Believe me I have taken no offense whatsoever. I am a complete n00b at programming in general and I know it. I will look into what you said and it turns out that there may be a programmer here that can help me. Thanks a lot for you help.

Also, the program that is already done was made by another guy and I am trying to work backwards from what he has done. Unfortunately, I do not even know how he coded it. He made an MFC .exe file and I don't know how that came about. If you have an idea about how I could modify this program he's...

Hey, thanks for the quick reply. This isn't for an assignment. I'm doing research at CSTAR and I was asked to see if I could figure out how to make the program I described above. Although I actually don't know anything about programming, I am happy that I at least have a chance to learn a little...

I am supposed to write a program using C++ that will take data collected by two separate DAQ cards and save them as either a text or spreadsheet file. Now, I'm still new at C++ and I do not even know where to begin. How am I even supposed to make a connection between Visual Basics and the DAQ...

Sorry I didn't reply back. I had to work on something else for the past couple of weeks. Thanks for that. I'll look into those things whenever I can. I do, however, have a more urgent task at hand and was hoping you could help me out. I am supposed to write a program using C++ that will take...

I am working on the development of an instrument which can be simply thought of as a cantilever tube. This tube is instrumented with strain gauges to measure the X/Y strains and two sets of rosettes, each consisting of two strain gauges at 45 degree. Note that the X/Y are 3-wire half bridge and...
