I have a text file containing 2,408,448 ascii floating-point values separated by spaces.
These represent height values of my local area (North Wales) arranged as 1344 rows wach containing 1792 columns.
I am trying to read these into a two-dimensional array that can then be easily 'cutup' into smaller tiles, at the
smallest level 1024 tiles 56x42 in size.

ImageJ accepted the following JavaScript statements :-

var DEM = newArray(numColumns);  // DEM = 'digital elevation model'
for(i=0;i<numColumns;i++)
{
DEM[i] = newArray(numColumns);   // this should create a 2D array
}

Attempts to fill the array so created (if it was) with this failed :-

DEM[row][column] =  some value.


Is there an alternative way of doing this ?
