how can I do time shifting of 0.001seconds in a dirac delta function and in a PN sequence. means i want p(n-.001) each time i try i get the following error :- Attempted to access PN1(1,0.999); index must be a positive integer or logical. my code is:

for x=1:1023 temporary = PN1(1,x); new_index =(x-delta); PN1(1,new_index) = temporary;

end

Hi Vaishali,

Matlab array indices must be positive integers. PN1 is a matrix or array. PN1(x,y) specifies the array element at row x and column y of that matrix. x and y do not act as inputs to any function.

i know this thing. but i have to do p(n-delta) so how can i do it ?

You will need to make PN1 a function. See here for how to make functions in Matlab.
