# can be used to index arrays, as below. If the right argument is an array, it will extract all elements represented by the indices on the right. If a multi-dimensional index is required, provide a subarray, such as [[2,3]] instead of [2,3]. To get the length of elements along a particular dimension, use the notation nd (For example, 1d to extract the size along the 1st dimension).
