    MATLAB Problems using integral function in Matlab

    hi kreil, I'm using x0=1.1225 ,which is the same value as the limit of integration. If you try again using that value on 'integrando', you'll see the result of the integral is a negative number which doesn't make any sense to me

    MATLAB Problems using integral function in Matlab

    Hi there! i have this function handle: integrando= @(x,landa,t) 1-exp(-((1/(landa*t))*((exp(-landa*x)/x)+((x-x0).*(1+landa*x0)-x0)*(exp(-landa*x0)/(x0^2))))); which as you can see using fplot(@(x) integrando(x,3,0.00063),[0 1.1225]) its value is constant (actually 1, and then starts...

    What are the Characteristics of Waves between 20 - 200 Hz?

    Why don't you listen to bass frequencies of music and human voice? It's precisely that interval

    Wheeler's Delayed Choice bibliography

    Hi, I'm in desperate search of an article related to Interaction Free Measuremnt and Measurement Theory: John Archibald Wheeler, "The 'Past' and the 'Delayed-Choice Double-Slit Experiment'," pp 9–48, in A.R. Marlow, editor, Mathematical Foundations of Quantum Theory, Academic Press (1978)...

    What determines frequency of oscillator in black body?

    Ok, my conclusion is that I should dissolve my "photon equals electron jump" dogma and wait and study the optical properties of materials. Anyway, I liked what Drakkith said about the mechanical nature of thermal energy (vibrational modes, rotation, translation too?) I find extremely hard to...

    What determines frequency of oscillator in black body?

    I'd like to recover the initial question: is it the case that black body spectrum is made up from an infinity of contributions of quantum transitions (electron, rotational modes, etc) which sum up to a continuous distribution? How complex should the chemical ingredients of the boundaries should...

    Proving (x^2)>0: A Simple Guide

    x belongs to R, not N, so I cannot apply induction

    No Constant Solution => No periodic solution

    Shall f be continuous function of two real variables. Proof that if equation x''=f(x,x') has not constant solutions, then neither it has periodic solutions.

    Infinite Variance VS Zero Variance

    Hi there, this is caco, I´m a new user from planet Earth. I´m studying Information Theory and lately It seems that I live in a fractal ocean of gaussian distributions... I do know that zero variance processes relate to Dirac´s delta distribution, my favourite mathematical artifact ever...
