SLICING IN A PROGRAMMING LANGUAGE

New D.I.C Head Joined: 1 May, 2008 Posts: 1	HI how do i implement slicing on a 3-d array( in a languagewhich of course does not support slicing). As in, how do i use the input parameters to get to the slice. For instance if i have a function 'slice' defined as : slice(row,column,depth) how do i use the combination of row,column and depth to figure out my slice-In Fortran 95 for example, doing something like Cube(2,:,:,) would give me the whole of the second layer of a 3 by 3 by 4 array.

How you would do it for a 3-D array depends on how you want to implement the 3-D array itself. If you have three dimensions, then the most obvious way would be to have three nested for loops to copy the data based upon the input parameters.
