In addition to support for vectorized arithmetic and relational operations, these languages also vectorize common mathematical functions such as sine. For example, if x is an array, then y = sin (x) will result in an array y whose elements are sine of the corresponding elements of the array x. Vectorized index operations are also supported.

The arrays V and COL_INDEX are of length NNZ, and contain the non-zero values and the column indices of those values respectively; COL_INDEX contains the column in which the corresponding entry V is located. The array ROW_INDEX is of length m + 1 and encodes the index in V and COL_INDEX where the given row starts.
As exchanging the indices of an array is the essence of array transposition, an array stored as row-major but read as column-major (or vice versa) will appear transposed. As actually performing this rearrangement in memory is typically an expensive operation, some systems provide options to specify individual matrices as being stored transposed.
