Hi,
I'm having a data in 3 dimensional array..as such i'm facing problems like java.lang.OutOfMemoryError:Java Heap space I thought of converting that 3 dimensional array to its equivalent 2 dimensional array..
The code that I was having is given below

Code:

for(int v=1;v<=clusters;v++)
			{
				if(minimum==Euclid[v])
				{
					clusterpointscount[v]++;
				
						
					for(int w=1;w<=columns;w++)
					{
						trackclusters[v][clusterpointscount[v]][w]=x[i][w];
						
						}
					}
				}

Instead of placing x[i][w] content into trackclusters[v][clusterpointscount[v]][w] i would like x[i][w] data to be placed in some array of this type: trackclusters[][]

o make it simple ... i want the data that is been stored in 3-dimensional array ie; trackclusters[][][] into 2-dimensional array of kind trackclusters[][]

eg: Points in cluster1:

0.33 0.0 0.0 0.0 0.5 0.0
0.5 0.0 0.0 0.0 0.67 0.0
0.67 0.0 0.0 0.0 1.0 0.0

Points in cluster2:

0.08 0.13 0.0 0.0 0.0 0.37
0.08 0.13 0.0 0.0 0.17 0.12

if trackclusters[1][1][1] represents the data that is present in Cluster:1 row:1 column:1
and trackcluster[2][2][1] represents the data that is present in cluster:2 row:2 column:1

instead of storing the data of Points in cluster in 3dimensional array.. i want to store them in 2 dimensional array

Somebody please help me out in this regard.
Thnx in advance

When you look at a three-dimensional array, the first argument
is an index which represents a pointer to a table in the array.
The second and third arguments are the row and column of the
table that the first argument is pointing to.

To change a three-dimensional array to a two-dimensional array,
you first must load the data into the three-dimensional array.
Then merge the tables in the three-dimensional array into a
two-dimensional array.

The reason why I asked a question of changing a 3-d array to 2-d array is as follows:
I'll be having all my data in an array x[rows+1][columns+1].. When I made of use of 3-d array like trackclusters[rows+1][rows+1][columns+1] I'll be wasting a memory of about (rows+1).For eg: if rows=3000 and columns=45, then see that I'm wasting about 3000 copies of memory. To overcome this problem I want to make use of
2-d array ratherthan using 3-d array..
so could you please give me some other solution for this?

If your data starts out in a 2-dimensional array, why did you store it in a 3-dimensional array? Why don't you put it in a 2-dimensional array and forget about the 3-dimensional array?

I really don't understand what you are trying to do.

Besides a 3-dimensional array isn't (row,row,column) it's (index,row,column).

A 3-dimensional array is used to store multiple tables, not just one table.

When you use a 3-dimensional array, a space for a table is reserved in memory
for every index that you specify. That takes up a lot more memory then one table does.

Thnx man for ur suggestions..
I got the thing working..

I'm glad. Hope I was of some assistance.
