WebC-contiguous, or simply contiguous arrays, refer to data that is stored row-wise, i.e. the indexing of data as stored in memory starts from the highest dimension. For one-dimensional arrays these notions coincide. For example, a 2x2 array A is Fortran-contiguous if its elements are stored in memory in the following order: WebC order# Same as row-major. column-major# See Row- and column-major order. contiguous# An array is contiguous if: it occupies an unbroken block of memory, and. array elements with higher indexes occupy higher addresses (that is, no stride is negative). …
