the description is like this the input is a zero-mean unit variance Gaussian white random sequence. Note that the beginning portion (about 5000 samples) of the signal should be dropped due to initial transient. how to use matlab code to achieve this Thanks

But it doesn't even make grammatical sense. I have no idea what you want. How many data point(s) do you want: 1 or 5000? Which of those element(s) are supposed to have a value of zero? What is random? The value? The location (x,y value)? Can you give an example with a smaller array, say one with 10 or 15 elements?

Now you get it? sorry for the not clearly explain my question

randomdata = randn(1, NumberOfSamples);
randomdata(1:5000) = 0;
