get.index.b: Internal function. Get the row index in the stacked sample matrices for the $b^{th}$ batch
Description
Internal function. Get the row index in the stacked sample matrices for the $b^{th}$ batch
Usage
get.index.b(batch.size, b)
Arguments
batch.size
vector of batch sizes
b
the index of the batch of interest
Value
the row index or sample matrices of batch b for all b's in b.vec
Details
In the computation, samples from each batches are stacked be rows to form x.mat,
as well as fx.mat, px.mat, qx.mat. To extract the samples from batch b and their corresponding
fx, px, qx values, the indices for batch b will be needed. They can be obtained by calling
get.index.b(batch.size, b)
