sum contents of array in groups of 10

3 次查看(过去 30 天)
My code produces a variable 'grains' which is a 1x3001 double.
I want to sum together the numbers in the first 10 cells, and repeat this in blocks of 10 cells until the end and save these in a new variable.
Please could somebody provide me with a starting point?

3001 is not exactly divisible by 10: what do you want done with the last element?

Where V is your 1x3001 vector:
M = sum(reshape(V(1:3000),10,[]),1)
