Hi,

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[,+]

or

round(round(t(Z[+,]+V[+,]) - (Z[,+]+Y[,+]),.01)

what is "t" in this command.

Thank you

T() is the transpose function.

The plusses inside square brackets are called "subscript reduction operators."
