MATLAB: Mean of each column entry

arraymeanstatistic

I have 2 arrays colA and colB, how can I get for example mean or other statistic of each entry of colB
I need to get something like this:
x = [-3084 -3085 -3086 -3087 etc]
y = [meanOfEachColB(-3084) meanOfEachColB(-3085) meanOfEachColB(-3086) meanOfEachColB(-3087) etc]
 colA   colB

I'd look into grpstats. See this example.
meanA = grpstats(colA,colB,'mean')
Another option is to use groupsummary. This might be helpful because it also returns the groups.
[meanA,grpB] = groupsummary(colA,colB,'mean')
