    [AVR] 16-bits Timer/Counter (Atmega2560) and Proteus

    I'm having problems with code execution in Proteus. The code has a delay time that is used to put the state of the output PORTB into 00000011 ( pin0 and pin1 "on") after the time set by the timer. One time the button is pressed the output state is changed and after a delay of 2s the output...

    Change polynomial representation ( MATLAB)

    Hi, How can I change a polynomial representation from x^2+ 6x + 10 to (x+3)^2 + 1 ? I used a <horner> function from MATLAB and the result was x*(x + 6) + 10. Anyway to have the above result " (x+3)^2 + 1 " using different function or arguments in matlab? Thanks.

    Rational Function (MATLAB)

    Hi, I´ve been trying to plot a rational function to see the graph of it. f(x) = (2x4-x2+1) / x2-4 From a book I´m following a graph is showed below : figure1 I created a script trying make a graph comes out. clear clc x =(-100:0.01:100); y = ((2.*(x.^4))-(x.^2)+1)./(x.^2)-4...
