0 The differential equation and the boundary conditions are satisfied. Another example. Now consider the BVP with a nonconstant coefficient: Integrating once yields (It is easier to perform this calculation in my head than to ask MATLAB to integrate 0.) I now perform the second integration: u=int(C1/(1+x/2),x)+C2 . u = 2*C1*log(1+1/2*x)+C2

Matrix eigenvalues can be computed with the “eig” function. Using , where Gss is a system in state-space format, will display the eigenvalues of the A-matrix of the system. As expected, executing this command for the state-space version of the feedback system yields the same result as the roots of the transfer function denominator.

To do this we continue to approximate the x-derivatives with finite differences, but think of the equation as a vector-valued ordinary differential equation, with t as the independent variable. SIMULINK solves the model using MATLAB's ODE solver, ode45.

Yet MATLAB not only allows this, but even encourages it, yielding the perfectly meaningful result 3.3333 which is consistent with the use above, and which is arguably the most meaningful solution of the “linear system” v x = w of four scalar equation in one unknown. Since the “matrix” v is not invertible, MATLAB “understands” that ...

A formula for the right hand side of the differential equation dy/dx=f(x,y) has to be saved as a function/procedure in an M-FILE. The following example (logistic equation: dy/dx=y(1-y)) exhibits the basic syntax: The filename is logistic.m, and it usually is saved in the root-directory of the C:-drive (in class), or in the subdirectory \matlab ...

Such substitutions will convert the ordinary differential equation into a linear equation (but with more than one unknown). By writing the resulting linear equation at different points at which the ordinary differential equation is valid, we get simultaneous linear equations that can be solved by using techniques such as Gaussian elimination ...

In its default mode of operation, SIMULINK uses a variable-step differential equation solver based on MATLAB's command ode45, so the entries of tout will not be equally spaced. To fix this, open the Simulation Parameters dialog box using the Edit menu in the model window, choose the Solvers tab, and change the Output options box to read ...
