This code creates a new matrix called A1, which is a subset of the original matrix A. A1 is created by taking all rows of A and only selecting columns 2 through 6. Then, each element in A1 is divided by the corresponding standard deviation of the respective column in A (which is accomplished by multiplying a vector of ones with the standard deviation of each column and then dividing A(:,2:6) by this resulting matrix). This process normalizes the data in A1 by scaling each column to have a mean of zero and a standard deviation of one.
