You have to describe what you want to do in more detail.

What specifically do you want to do with Column 2 and Column 3?

Just use the : operator in the row position to collect all rows and a specific column number in the column position. NB: also that * is matrix multiplication so if you want the element-wise multiplication as would presume from the question you do, you have to use the "dot" operator .*

p=x(:,2).*x(:,3);

assuming the array read from Excel is in variable x
