I am wondering what these comments mean in SAS if Z ,Y, and V are defined as a n by n and n x m and n by k matrices:
Z[+,] or Z[,+]
round(round(t(Z[+,]+V[+,]) - (Z[,+]+Y[,+]),.01)
what is "t" in this command.
T() is the transpose function.
The plusses inside square brackets are called "subscript reduction operators."
Thank you so much!
