+ * Algorithm
+ *
+ * In a inner loop, the parameters from SSET are translated into temporary

+ * We define the stride, count and block to be 1 in the row dimension to achieve

+ * In each iteration, the 2D block is displayed in the inner loop. The remaining
+ * slower dimensions above the first 2 are incremented one at a time in the outer loop
+ *
+ * The element position is obtained from the matrix according to:
* Given an index I(z,y,x) its position from the beginning of an array
* of sizes A(size_z, size_y,size_x) is given by
* Position of I(z,y,x) = index_z * size_y * size_x
