Current directory
Hi folks, I am puzzled by the behaviour of current directory in R2008b. Please do you know the way to ensure that only one path is active and the directory does not change?

applied maths
Hello I am having a little problem! Basically I need to plot a function of k,y so this is my script syms k y f=100; h=150; c1=1450; c2=1650; b=1.2; w=2*pi*f; a=w*h*sqrt(1/(c1*c1)-1/(c2*c2)); g=sqrt(w/c1*w/c1-k*k); y=g*h; tan(y)==(-b*y)/sqrt(a*a-y*y) plot(k,y); However the first problem was the ... 18 May 2010 17:00

For some reason the default opening location for my MATLAB figures it ouside of the screen area of my monitor. How do I change this? Put another way, when I call "figure" the window opens, but half of it is off the screen. This is very irritating. ... 18 May 2010 14:46

calculating conditional moments in EGARCH model
I am trying to estimate the conditional moments in an EGARCH model, but I am confused by the discrepancy between the simulated and analytical results that I get for mean and variance. First, I estimate an EGARCH(2,1) model: [GARCHCoeff,Errors,LLF,e,s,Summary] = garchfit(Spec, SampleR); Then I use garchpred() t... 18 May 2010 11:27

ODE Help
Hey folks, I'm having some difficulty with syntax/understanding around the ODE functions. What I'm working on at the moment is a function, BigFunction(6 parameters) that returns a 19 element answer. I then need to apply ode23tb to this answer for 10 steps - but I'm getting well hung up on the syntax for these things... 18 May 2010 13:39
