Matlab for summation

  1. Sep 23, 2010 #1
    Hi,

    I am trying to write a code for summation in matlab. I have two different text files with T and t in them.... I need to write a code that calculates....

    http://yfrog.com/5ocalculationj

    So, I have T1, T2, T3,T4,,,,,,, and t1 t2 t3 t4.... and i need to use the above equation.... this is the code i wrote...

    clc
    clear all
    load time.txt
    load temperature.txt

    T = temperature;
    t = time;
    for i = 1:149
    x(i) = [T(i+1)-T(i)]/[sqrt(t(150)-t(i+1))+sqrt(t(150)-t(i))];
    end
    x
    y(1)=x(1);
    for j = 2:149
    y(j) = y(j-1) + x(j);

    end
    y
    for m = 1:149
    q(m)= 41904.076*y(m);
    end
    q
    t_1 = t(1:end-1);
    plot (t_1,q)
    grid on



    the number 41904.076 is the value of the constant...

    I dont know what is wrong with the code but i am not getting the result i should be getting... any suggestions ??


    Thanks in advance....
