The coefficients for the intervals can be summarized as interval a b c d 1 70 0 Note that we are plotting the points as depth versus temperature so that the graph depicts how the temperature changes down through the tank. The coefficients for the intervals can be summarized as interval a b c d 1 0 0. This occurs after 12 iterations with the result that y 0.
The remaining values can be computed in a like fashion to give t y 0 1. The plot, along with the linear regression best fit line is shown below. The Eulode function can then be used to generate results and display them graphically.. Here are the first few steps. The remainder of the computation would be implemented in a similar fashion and the results displayed in the plot below. Here are the first few steps along with the analytical solution.
A plot of all the values can be developed and indicates the same close agreement. The first program shown below is strictly developed to solve 2 equations. Here is the test of the solution of Prob. This is also illustrated by a state-space plot y versus x : 16 12 8 4 0 0 4 8 12 16 b RK4. Here is the first step in detail.
Although the pattern might appear random, an underlying pattern emerges when we look at the state- space plots. For example, here is the plot of y versus x. However, the state-space representation looks much more consistent.
Thereafter, they abruptly begin to diverge. The reason for this behavior is that these equations are highly sensitive to their initial conditions. After a number of steps, because they all employ different algorithms, they begin to diverge slightly. When the discrepancy becomes large enough which for these equations is not that much , the solution will tend to make a large jump. Thus, after awhile, the various solutions become uncorrelated.
Such solutions are said to be chaotic. It was this characteristic of these particular equations that led Lorenz to suggest that long-range weather forecasts might not be possible. The second step can then be implemented with the non-self-starting Heun method: Predictor: y 0.
A plot of the entire solution is also displayed t y 0 0 0. The best way to do this is with LU decomposition since we will have to solve the system repeatedly. For the present case, because its easier to display, we will use the matrix inverse to obtain the solution. Very tiny round off errors in the numerical solutions bring it to the fore. Hence all of the following solutions eventually diverge from the analytical solution.
The plot shows the numerical solution bold line along with the exact solution fine line. First, because the displacement is small, the linear solution provides a decent approximation of the more physically realistic nonlinear case.
Second, the two solutions diverge as the computation progresses. After 10 iterations, the relative error falls to 0. First, the matrix can be put into the proper form for an eigenvalue analysis by bringing all terms to the left-hand-side of the equation.
First, the matrix can be put into the proper form by dividing each row by 0. After 9 iterations, the method does not converge on the highest eigenvalue.
Rather, it converges on the second highest eigenvalue of 7. Related Papers. By Leger Fernandez. Nise Solution Manual 6th edition. Come and download control system engineering absolutely for free.
