I have the following column vector called A:
What I want is a code that will take every 3 data points in A and put it in its own separate row in a new matrix called B. After the first 3 elements or data points in A has been selected and placed in the first row in B, the code should then select the next 3 data points and place them in the 2nd row in B and so on.
e.g., the 1st row in B will be 1,2,3, & 2nd row will be 4,5,6, & 3rd row will be 7,8,9 and so on until every 3 data points in A has been selected and placed in its own row in B.
