polyval help: finding the root
I've just created a straight line with polyval on some data, and I was wondering whether it was possible to find the x value when the polyval becomes zero? this is what I have got A = [a1,a2]; B = [b1,b2]; p = polyfit(A,B,1); f = polyval(p,x); hold on; plot(x,f,'r'); I want x @ f = ... 27 Jul 2010 04:04

ginput crosshair error/bug
On one figure when i use the "ginput" command Matlab does not fill in the figure displayed underneath the cross-hairs when i move them. What i mean is that when i move my cursor the black cross-hairs move with my cursor, but it leaves behind a white "shadow" where the cross-hairs used to be.

Unable to interpret TeX string
Hello, I am trying to show in the xlabel of a graph the symbol of derivative over a greek letter, and I receive the error described in the subject. Here it is my code: xlabel('\textbf\dot{\theta}','interpreter','latex') or xlabel('\bf\dot{\theta}','interpreter','latex') They don't work. Is there a pr... 22 Jul 2010 13:35

How to convert between convolution and corrleation? And more on FFT. Thanks a lot.
Dear all, What's the relationship between correlation and convolution? For example, if \otimes denoting convolution operator and * denoting correlation operator, "A * B" can be written into what form of correlation? "B^T \otimes A" is incorrect, I think. But how to convert? Furthermore, how to convert a convoluti... 22 Jul 2010 23:28

Wolfram Alpha - Integrate - bug and glitch - 1996 - 2010 (!)
For the same integral, Wolfram Alpha returns TWO invalid answers, see the pdfs below: Integrate[Sin[z]^2/Sinh[z]^2, {z, 0, Infinity}] (1/4)*(-1 + 2*Pi*Coth[Pi]) = 1.32667 (often) -3/4 (very rarely) Both of them are wrong as NIntegrate[Sin[z]^2/Sinh[z]^2, {z, 0, Infinity... 22 Jul 2010 10:17
