Let solve the problem again with h = (x = 0.2. We now have 9 unknowns that can be solved from the following system. Ay = r. where. A = y = T. r = T. Applying finite difference method to an ordinary differential equation, we obtain tridiagonal matrix equations of the form = For example 6.1-1, we have. ai = 1, i = 1, (, 9. bi = ( [2 + (x2(1 ...

Matrix equation is used in solving linear simultaneous equations. For matrices of order 2 or 3, the calculation is simple and can be done on paper. However it is when one encounters matrices of larger orders that this computation becomes tedious and sometimes impossible without computer programs. A simple MATLAB program can be scripted to solve ...

We begin with a matrix A whose rows correspond to the labor, fabric and padding equations. We will add an additional row at the bottom to correspond to the profit equation: y - 2x1-5x2=0. Here, y denotes the profit, and we can prefix a column corresponding to y whose only non-zero entry is a 1 in the last row. This gives us the matrix

To find eigenvectors and eigenvalues, we need to solve the equation. We can rewrite this as . where I is the identity matrix. (The identity matrix is a square matrix that has 1s on the diagonal line and 0s elsewhere.) ... The determinant of a matrix can be computed in MATLAB. Define a square matrix A. Then the command is >>det(A)

To solve the same problem using MatLab, we construct a matrix equation and then solve it using the built-in solver in the program. To facilitate this, we write the difference equation as: By writing this at the four internal mesh points, we obtain: Since we know the boundary values, we can write: or . Now we would like to write this as a matrix ...

We can also solve the heat equation using SIMULINK. 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…

Let be the solution matrix to the equation . I.e., . Now, solve algebraically each for xi. This creates a new set of equations, , where refers to the set of unknowns {xj} excluding xi. Algebraically, this looks funny, because each unknown is expressed in terms of all the other unknowns, hence the term implicit. Of course, what we really mean is.
