I have a 76x5 matrix and would like to convert this to a 76x1 matrix whose rows are the mean of each of the rows of the original matrix. Can anybody help me?
Thanks in advance.

A=rand(76,5); m=mean(A,2);

Did you happen to look up the help for the mean() function? If you had, you would have seen that you can specify the dimension along which to compute the mean.
rowMeans = mean(your2DArray, 2);

Very strange that you tried my answer and had some difficulties with it and then you tried Mitch's answer and had it work when our two answers are 100% identical, other than the names of the variables. I have no explanation unless I see your code. Sorry you wasted an hour with my code.

+1. Your code is trivial, but the suggestion to read the help text of MEAN is perfect, because it will solve 10.000 further questions very efficiently.
I do not understand, why Mitch accepts his own answer.
