Hello, I want to create a triangular matrix and only keep the lower
triangle entries without having to allocate memory for the whole
matrix, is there any way I can do something like
A<-matrix(data, nrow=50)
but for a triangular matrix?
The `Matrix` package implements sparse matrices and has several
triangular classes.
