Proper releasing dynamic allocated memory

Hi,
I have allocated memory for 3-dimensinonal array in this way:

1
2
3
4
5
6
7
8
9
10
 
Matrix ***channel_coefficient;
channel_coefficient=new Matrix**[drop_number];
for(int i=0;i<drop_number;i++)
{
channel_coefficient[i]=new Matrix*[N];
        for(int j=0;j<N;j++)
        {
         channel_coefficient[i][j]=new Matrix[sample_number];
        }
}

where Matrix is matrix data type

My question is, if following code is valid for releasing memory for above array?

1
2
3
4
5
6
7
8
9
 
for(int i=0;i<drop_number;i++)
{
        for(int j=0;j<N;j++)
        {
        delete[] channel_coefficient[i][j];
        }
 delete[] channel_coefficient[i];
}
delete [] channel_coefficient;

I would be grateful for any comments.
