wav dimentions are
wav = 5001*1
and I want to change it as wav = 5001*5
How I can reshape it?

So you want to take 5001 values and generate 25005 (5001 times 5) values using those values. How do you want to generate the additional 20004 values?
Make duplicate copies?
x = (1:6).'
y = repmat(x, 1, 5)
Offset the copies by a certain amount? This approach uses implicit expansion; if you're using an older release you could use bsxfun.
x = (1:6).'
y = x + (0:10:40)
Pad with 0 values or with random data?
x = (1:6).'
y = [x, zeros(size(x, 1), 5)]
z = [x, rand(size(x, 1), 5)]
w = [x, randi([7 11], size(x, 1), 5)]
Something else? If so, please explain in detail how you want to generate the additional values.

I want to generate duplicate values (5000) in five columns rather than one...

His code does that, Just write this.
x = (1:5000).';
wav = repmat(x, 1, 5).

This should work
wav = 5001*1
wav = wav*5

It is not working, perhaps I'm unable to explain my point...
the size of wav is 5000 1 and I want reshap it as 5000 5

Wait 5000 rows and 1 column?

5000 rows and 5 columns, each column is duplicate of other.
