How to sum a specific number of observations through an entire dataset ?

Sir i have a dataset (say m(750,1)). I have to sum 75 observations from beginning . Means i need sum of 1-75, 76-150, 151-225 ....676-750 observations so that i get the result as m_result(10,1). Would you please help me?

TRAILOKYA, if it is a numeric array use reshape

 m_result = sum(reshape(m,75,[]));
