I have a vector of temperature measurements every minute over a day and I need to convert this to a vector of 30 minute averages over the day. Any suggestions of how to do this effectively? Thanks

Where do you have the timestamp? Is it a two column matrix with first column the timestamp and the second column the measurment?
Please provide a concise example by editing your message and apply formatting.

Since you have reading one minute apart, you should have 24*40=1440 readings. You need 48 readings, i.e. mean from 1-30, 31-60 etc.. YOu can reshape your actual vector pf readings and find the mean as follows, Suppose A is you vector of 1440 readings
b=reshape(a,30,[]); % this reshapes your vector into 48 vectors
mean(b); % this finds the mean of each
