Question:

Use MATLAB to create a state-variable model; obtain the expressions for the matrices A, B, C, and D, and then find the transfer functions of the following models, for the given inputs and outputs.
a. The outputs are x1 and x2; the input is u.
1 = -5x1 + 3x2
2 = x1 - 4x2 + 5u
b. The output is xi; the inputs are u1 and u2.
1 = -5x1 + 3x2 + 4u1
2 = x1 - 4x2 + 5u2
