arithmetic mean symbol
Hi, I would be grateful if someone can let me know how to show in matlab figure e.g. in ylabel arithmetic mean symbol ( line above the letter)? One way is to write >> ylabel('Tmean - T5'); but I want to use short line over T indicating arithmetic mean without writing 'mean' by word. Thank you, Boris ... 21 Jul 2010 01:35

MuPAD: straightforward simplification
Hi all, I'm new to MuPAD and symbolic computation. I have this coming from previous computation: a + b -2*c How can I convert that into: (a - c) + (b - c) ? Another example: Given a*b + a*c - 2*a*d + b*c - 2*b*d - 2*c*d + 3*d^2 How can I convert that into: (a-d)*(b-d) + (a-d)*(c-d) + (b-d... 21 Jul 2010 23:29

How to calculate the expectation of (U-V)+
Hello, There are two independent random variables U of gamma distribution G(u,lambda1) and V of gamma distribution G(v,mu) where lambda1=0.45 and mu=1.0. Now I need to compute E[(V-U)+], i.e. E[max{(V-U),0}], which equals the double integral of the following function (note that mu=1.0, thus it can be omitted): ... 22 Jul 2010 01:38

Removing scaling label from axis?
Dear Matlab Users, Matlab typically puts a scale factor (i.e. x 10^5) on an axis when the units are too large to display. For example, in Matlab r2008b: plot(linspace(0,100), linspace(0,1e6)) will produce y labels of 0 to 10 x 10^5. I would like to eliminate this as in my application the axis consists of Mat... 21 Jul 2010 00:31

running compile functions using fitoptions
Hi All, I'm trying to run an application that I've compiled using mcc. I've reduced the function to show the exactly line problem, and show it bellow. function a = testm(b) fo=fitoptions('method','SmoothingSpline','SmoothingParam',0.60000000000000000555); a=0; end I can compile it properly with this ... 21 Jul 2010 18:01

xPC R2009a: overflow range error in pow
I am in the process of upgrading from R2007a to R2009a. My model, which I run on xPC target works great with R2007a, no problems, been using it for years. I use Watcom compiler v 1.3 for R2007a. When updrading to R2009a, using the same model, same target hardware, Watcom compiler 1.7, I get an error message on the t... 22 Jul 2010 18:00
