Detailed Description

Calculate the Kronecker product of two matrices.

Compute the Kronecker product of a matrix. This outer product is a block matrix such that if the input matrices are (m by n) and (p by q), then the output matrix is (mp by nq).

float ha[] = {1, 3, 2, 4};
float hb[] = {0, 6, 5, 7};

array a = array(2, 2, ha);
// a = 1 2
//     3 4

array b = array(2, 2, hb);
// b = 0 5
//     6 7

// Create space for the result
array c = array(4, 4, f32);

float* da = a.device<float>();
float* db = b.device<float>();
float* dc = c.device<float>();

af_kronProd_SS(dc, 2, 2, da, 0, 2, 2, db, 0);

print(c);
// c =
//     0.0000        5.0000        0.0000       10.0000
//     6.0000        7.0000       12.0000       14.0000
//     0.0000       15.0000        0.0000       20.0000
//    18.0000       21.0000       24.0000       28.0000
