    Ensuring Peaks Near Middle & Calculating End Value of "u" in MATLAB

    u(i,end) = u(i,end-1)+10*(log(10*exp(-0.0001*u(i,end))))*(1-(log(10*exp(-0.0001*u(i,end))))/100)*dx; that is the line that is giving me problems. Basically, when I run this simulation I get peaks occurring at the boundaries - instead, I want peaks to occur in the centre. Can I do this by the...

    Ensuring Peaks Near Middle & Calculating End Value of "u" in MATLAB

    1. In the below code, I need to know how to ensure that the peaks end up near the middle. I also want to know how to calculate the end value of "u". Thanks! 2. clear all close all clc u = 1000*ones(1,200); dt = 0.01; dx = 1/201; for i = 2:10/dt dudt = diff(u(i-1,:)); Du =...

    How to Derive ((A>B)>A)>A Using Sentential Logic?

    [b]1. How do you prove, using SD, that ((A>B)>A)>A? [b]3. I tried to first assume (A>B)>A. Then I made a sub-derivation, assuming ~A. In this sub-derivation, I need to derive a contradiction. How?
