By default, the independent variable is t, and the transformation variable is s. syms a t y f = exp (-a*t); F = laplace (f) F =. 1 a + s. Specify the transformation variable as y. If you specify only one variable, that variable is the transformation variable. The independent variable is still t. In general the inverse Laplace transform of F (s)=s^n is 𝛿^ (n), the nth derivative of the Dirac delta function. This can be verified by examining the Laplace transform of the Dirac delta function (i.e. the 0th derivative of the Dirac delta function) which we know to be 1 =s^0.Laplace Transform explained and visualized with 3D animations, giving an intuitive understanding of the equations.
