Upsample
Upsample[array, n]
returns an upsampled version of the array by inserting 
zeros between array elements.
Upsample[array, n, offset]
shifts array so that its first element moves to the position offset in the resulting array.
Upsample[array, n, offset, val]
inserts 
elements of value val between array elements.
- In Upsample[array, n, offset], the offset has to be a number between
and n.
- In Upsample[array, ...], array can be an array of any rank.
- Upsample[array, {n1, n2, ...}] inserts
zeros between elements in the i
dimension.
- Upsample[array, n] is equivalent to Upsample[array, n, 1].
Upsample a list by a factor of 3:
| Out[1]= |  |
Use an offset:
| Out[2]= |  |
Specify the value to be inserted:
| Out[3]= |  |
Upsample a 2D array:
Out[1]//MatrixForm= |
| |  |
Use a different upsampling factor in each dimension:
Out[1]//MatrixForm= |
| |  |
Upsample a symbolic array:
| Out[1]= |  |
