Hello, Does anybody know how to use Mathematica4.1 to get the following inverse laplace transform? I have 8 parameters, a,b,c,d,w1,w2,w3,w4. (Where there is a constrain that a+b+c+d=1) The following is the script I tried. ------------------------------------------------------------- f4s=aw1/(s+a)+bw2/(s+b)+cw3/(s+c)+dw4/(s+d) fi=f4s/(1-f4s) InverseLaplaceTransform[fi,s,t] ---------------------------------------------------------------- I tried to run it, but mathematica runs for ever and can not give me an answer. Thanks for your help! David _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
