Could anyone help me how to write the attached expression in matlab

[Walter Roberson]

Is it correct that that is intended to be a recursive definition for tau ? If so then we would need to know t_0 in order to calculate the other values.

Answer 1

[Yuvaraj Venkataswamy]

if true
  M=yourInteger; % greater than 1
  for k=0:M-1
      t(M-1)=[M-1;k].*t(k)
  end
end

[Walter Roberson]

Unfortunately not. The notation

(M-1)
(k  )

is the number of combinations of (M-1) choose k,

nchoosek(M-1, k)

Also, you are assigning to the same location t(M-1) each time, and you are not doing a summation.

Yes sir. You are correct. But, in the attached figure, the notation is look like a vector. In that case, I did. Thank you.
