Detailed Description

Struct for a non-mutable sub-vector.

For a sub-vector vec, the corresponding entries in the global vector x(j) (one based) are as follows:

x( vec.global_offset + k )
  = vec.values[ vec.value_stride * (k-1) ]

for k = 1,...,vec.sub_dim

The stride member vec.value_stride may be positive (>0), negative (<0) or even zero (0). A negative stride vec.value_stride < 0 allows a reverse traversal of the elements in vec.values[]. A zero stride vec.value_stride == 0 allows a vector with all the elements the same.

To avoid making mistakes in setting the members of this struct use one of the helper functions RTOp_sub_vector(), or RTOp_sub_vector_null().
