Hi, Is there a quicker way than creating a new larger matrix (I've seen a discussion 3 years ago on adding a row to a matrix)? Is there an alternative means of creating a look-up table of values? Regards, Tim

Hello Tim, there are stack() and augment() functions, as well as direct assignment of an element outside the boundaries, that automatically increase the matrix size to include the new element Edited by user 08 June 2017 03:19:31(UTC)
