Please I need helpe implement this codes:

Z_transform(X, r ) /*X: N d matrix; r 1: Z spaces degree. */ 1 if r = 1 then return X 2 for i = 1 . . . r do 3 B [i ] = (i +d 1 d 1 ) // |Bi |. Expensive to compute. Save them for reuse. 4 d r i =1 B [i ] // #features in Zspace 5 ZX.copy // Better not change users data. 6 Create `[0 . . . d 1]; 7 Init `[0 . . . d 1] {0, 1, . . . , d 1} /* Create B2, . . . , Br ; append them on the right side of Z*/ 8 q 0 // Total size of all buckets before the previous bucket. 9 p d // Total size of all previous buckets 10 g d // index of the new column in Zthat is being computed 11 for i = 2 . . . r do // Create B2, . . . , Br 12 for j = q . . . p 1 do // Process every element in Bi 1 13 for k = `[j ] . . . d 1 do 14 temp Z[:, j ] X[:, k ] // * is element-wise multiplication 15 np.append(Z, temp.reshape(1, 1), 1); 16 `[g ] k ; 17 g g + 1 18 q p // Total size of all the previous bucket 19 p p + B [i ] // size of the bucket thats just computed 20 return Z
