how do you take the mean across columns but for singular row in a 960x31 array

help!!

I have 960 rows in all the cells there are reaction times, then there are 31 columns, I cant remember how to do this

[Walter Roberson]

mean(YourArray(ColumnToSelect,:))

Or perhaps what you are looking for is

mean(YourArray, 2)

to give you 960 means of columns.
