Split an array into train and test sets

This procedure splits an array into two sets along one dimension. The array can be of any rank, but the dimension along which to split must be specified. An optional index array can also be split. The size of the left and right splits can also be specified. The data can be shuffled before splitting.

Module Procedures

private subroutine split_2Drdata_1Drlist(data, label, left_data, right_data, left_label, right_label, dim, left_size, right_size, shuffle, seed, split_list)
