Hello, I am new to matlab and I try to find a solution to a simple problem I have.
I have a column of values and I want to calculate mean values with a certain step, e.g. calculate the mean of values 1-6, then the mean of values 7-12 etc ...
Can someone please give any ideas on how to do this?
Thank you, George

The reshape command can help to implement this:
X = rand(18,1)
Y = reshape(X,6,[])
mean(Y)
or more simply, just:
mean(reshape(X,6,[]))

assuming x is the vector:
mean(x(1:7));
mean(x(7:12));

Thank you both for your answers. I hadn't thought using the reshape function, it worked fine.
