I have data in a matrix where I need each consecutive row to be the average of all the rows above this. How would I go about this?

Assuming the average includes the row in question:

x = your matrix
result = cumsum(x)./(1:size(x,1))';

Or for earlier versions of MATLAB:

result = bsxfun(@rdivide,cumsum(x),(1:size(x,1))');
