Matlab ilaplace command questions

  1. Jan 31, 2010 #1
    I am using the ilaplace command from matlab and it keeps spitting out the dirac delta function. I typed the exact command in the matlab help section and it still gives me this. for example I type in this...


    and I get this...

    1 - dirac(t)

    below is a copy of matlab help file that has this exact command with the result I'm after.

    syms s t w x y
    ilaplace(1/(s-1)) returns exp(t)

    Any help would be great. I'm thinking it is some format command or something beforehand.

    I think you must have mistakenly typed it as >> ilaplace(1/s-1)
    Thats why you got 1 - dirac(t).

    I'm not quite sure what you mean? Sorry for the much delayed response.

    EDIT: AHH I see what your saying now with the parentases!!
