    MATLAB Matlab function errors while using loop

    To define your own functions you must save them in .m files, not just type them into the command line. To create a new function, go to File -> New -> Function and you will get a shell for a new function. If you want to start completely from scratch, you can go to File -> New -> Script. Once...

    Confidence interval for estimated mean of (discrete) uniform distribution

    New reply since I cannot edit my last post: It's become painfully obcious to me that I do not currently have the time to pursue this ("a few days"... pfft >_>) Hopefully I will be able to pick this up again at a later point in time. Until then, thank you Stephen Tashi and SW VandeCarr for...

    Confidence interval for estimated mean of (discrete) uniform distribution

    I've read both your posts and thank you for the assistance so far. I'm currently digesting it and trying to give it some more thought on my own, but I don't have very much time to spare at the moment. I will try to come back in a few days with comments and more questions.

    Confidence interval for estimated mean of (discrete) uniform distribution

    This is strictly for my own uses, so tradition is not an important aspect. I read briefly in the articles on credible intervals and confidence intervals and just want to paste in the following (if for nothing else, so that I can access it easier in this thread): With that said, what I...

    Confidence interval for estimated mean of (discrete) uniform distribution

    None taken. I want to be able to give an interval within which I can with a given certainty (e.g. 95%) say that the mean of the distribution (not the sample) lies.

    Confidence interval for estimated mean of (discrete) uniform distribution

    Say that there is a random variable X ~ U(a,b) where U is the discrete uniform distribution on integers on the interval [a,b]. Sample n such variables with the same (unknown) parameters a and b. Using those samples it's possible to estimate the mean either by taking the sample mean (sum the...

    MATLAB Plotting XYZ Coordinates in 3D with Matlab

    I would use the 'plot3' command to plot the points and then use 'quiver3' to plot the arrows between the points. For making your data points look (somewhat) as spheres, look into the documentation for "linespec" (line specification) and adjust it appropriately when you call the 'plot3' command.

    Why do simple balances always come to rest in a horizontal position ?

    [SIZE="1"](click for a larger version) This is supposed to be a balance, rotating around point A with loads at point B and point C. For a balance such as this to be at rest, we must have equilibrium for forces in the x-direction, the y-direction (both implicitly defined in the image by the...
