Important built-in linear algebra functions:

Important functions of Matlab's Symbolic Math Toolbox (SMT):

Important function of the Control System Toolbox:

Important built-in linear algebra functions:

  • r = rank(A) - Compute the rank of matrix A
  • Ker = null(A) - Compute an orthonormal basis for the kernel space of matrix A
  • Im = orth(A) - Compute an orthonormal basis for the image space of matrix A using Gram-Schmidt orthogonalization
  • A_GJ = orth(A) - Compute the reduced row echelon form of matrix A (Gauss-Jordan elimination)

Seminar 1. - Laplace transformation, non-dimensional ODEs

Matlab examples

  1. Compute a polynomial division (see lecture notes nr. 3).
  2. Compute the partial fractional decomposition of $H(s) = \frac{5s^2+3s+1}{s^3+6s^2+11s+6}$.

    syms s
    H = (5*s^2 + 3*s + 1)/(s^3 + 6*s^2 + 11*s + 6);
    partfrac(H)

    Output:
    ans = 3/(2*(s + 1)) - 15/(s + 2) + 37/(2*(s + 3))
    $H(s) = \frac{3}{2(s+1)}-\frac{15}{s+2}+\frac{37}{2(s+3)}$

  3. Compute the Laplace transformation of $h(t) = \cos(at)+\sin(at)+e^{-ct}\cos(bt)+e^{-ft}\sin(et)$.

    syms t a b c e f
    h = cos(a*t) + sin(a*t) + exp(-c*t)*cos(b*t) + exp(-f*t)*sin(e*t)
    laplace(h,t)

    Output:
    ans = a/(a^2 + t^2) + (c + t)/((c + t)^2 + b^2) + e/((f + t)^2 + e^2)
    $H(s) = \frac{a}{a^2+t^2}+\frac{t}{a^2+t^2}+\frac{c+t}{{(c+t)}^2+b^2}+\frac{e}{{(f+t)}^2+e^2}$

  4. Compute the inverse Laplave transformation of $H(s) = \frac{1}{s^2 + s + 1}$.

    syms s
    ilaplace(1/(s^2+s+1))

    Output:
    
    
            $h(t) = \frac{2\sqrt{3}{e}^{-\frac{t}{2}}\sin(\frac{\sqrt{3}t}{2})}{3}$
