fr.rar - Write a Matlab program which solves the initial value problem
y
= (xy − y2)/x2, y(1) = 2,
by the order four Runge-Kutta method, over the interval [1, 3] using steps of h = 1/128. The exact solution to
this problem is given by y(x) = x/(ln x + 1/2).
Your program should display a plot of the Runge-Kutta solution and the exact solution on the same axes
and should print out the norm of the relative error of the numerical solution. Be sure to label the x,y axes of
the plot and to put a title on the plot.,2009-06-12 00:44:47,下载4次
ww.rar - Modify the Matlab Gauss Elimination routine given in lectures so that it
(a) performs implicit complete pivoting, and
(b) handles m right hand sides at once by performing an LU decomposition of the matrix A first and
then doing forward substitution and back substitution (hence not modifying the right hand side as the
elimination is perfomed).
Test your program and then run it on the system AX = B,2009-06-12 00:42:22,下载13次
