How to represent a laplace system in matlab?

[neoflash]

How can I realize a system H(s)=a-b*e(-s*T) in matlab and view its group delay?

Thanks,

also how to simplify a matrix into a vector

such as from 1x1x100 to 100?

i dont knw wat u mean by realizing that function in matlab but MATLAB offers may functions to analyze the systems in s-plane. freqs, freqresp, tf (trasfer function), etc...

n 1x1x100 matrix to 1x100 or 100x1 ?...u can use 'reshape' function in MATLAB.

hope this helps..
