Multi-dimensional Arrays · The Julia Language

WebThe Array type is a specific instance of DenseArray; Vector and Matrix are aliases for the 1-d and 2-d cases. Very few operations are implemented specifically for Array beyond those that are required for all AbstractArrays; much of the array library is implemented in a generic manner that allows all custom arrays to behave similarly. Web(which can also be given as a tuple) to generate arrays of random values. In a multi-threaded program, you should generally use different RNG objects from different threads or tasks in order to be thread-safe. However, the default RNG is thread-safe as of Julia 1.3 (using a per-thread RNG up to version 1.6, and per-task thereafter).
