Hello,

asdasd

I got a matrix like this:

Now I would like to create another vector with the means of each line:

b(4,1)
b=
1,67
2,67
2,67
3

How can I do this with Matlab?

I tried this code but it only takes the first line...

b=mean(a)

Thanks for your help!

Look at the description of the dim input argument in the documentation for the mean function. There's also a relevant example on that documentation page.

doc mean
