I need to transform the following function to the symbolic form to evaluate it with arbitrary precision.
Z(N,Thetas) = prod((1 - exp(-(N:-1:2).*Thetas))./(1 - exp(-Thetas)),2)
where Thetas is matrix M x N-1 of the positive real numbers. So the expected result is vector Z (M x 1). I am not able to rewrite function Z to symbolic form and than evaluated it by vpa() command.
Any idea how to effectively solve it?
