Detailed Description

Creates an array with [0, n] values along the seq_dim which is tiled across other dimensions.

// Generates an array of [0, 4] along first dimension
array a = range(dim4(5));        // a = [0,
                                 //      1,
                                 //      2,
                                 //      3,
                                 //      4]

// Generates an array of [0, 4] along first dimension, tiled along second dimension
array b = range(dim4(5, 2));     // a = [0, 0,
                                 //      1, 1,
                                 //      2, 2,
                                 //      3, 3,
                                 //      4, 4]

// Generates an array of [0, 2] along second dimension, tiled along first dimension
array c = range(dim4(5, 3), 1);  // c = [0, 1, 2,
                                 //      0, 1, 2,
                                 //      0, 1, 2,
                                 //      0, 1, 2,
                                 //      0, 1, 2]
