del_vt = 1e-3:1e-3:100e-3;

% z is a function of del_vt  of order [1 100]

test = PDF_DEL_VT_tsts(del_vt, z);

The function is defined as..

function out_pdf = PDF_DEL_VT_tsts(del_vt, z)
mu_it = 9;
out_pdf = exp(-mu_it)*(dirac(del_vt) + z);
end

I am getting this error.. Please help soon. 
??? Subscript indices must either be real positive integers or logicals.

Error in ==> single_defect_pdf at 101
test = PDF_DEL_VT_tsts(del_vt, z);

Hi, I don't see anything wrong with your function

function out_pdf = PDF_DEL_VT_tsts(del_vt, z)
mu_it = 9;
out_pdf = exp(-mu_it)*(dirac(del_vt) + z);
end

that would produce that error. Is it possible that you have a vector in your workspace named PDF_DEL_VT_tsts? Or maybe inside this single_defect_pdf file. It looks like an error you get when you are trying to access some element of a variable with an invalid index.

If you enter

>>which PDF_DEL_VT_tsts

what is returned?
