function delta

Creates a delta function. This is defined by: All values in the array 0 except for (x, y) which is set to value. If value is not set, 1 will be used. Optional keywords are naxis1, naxis2 which determine the size of the array. If not set, the size of the array is determined from global variables.

Syntax
result = delta(X, Y [, VALUE] [, naxis1=value] [, naxis2 = value])

Arguments
X:   The x-position of the nonzero pixel
Y:   The y-position of the nonzero pixel
VALUE:   Optional, the value of the nonzero pixel
naxis1=value:   Optional, the size of the resulting array in the first dimension
naxis2=value:   Optional, the size of the resulting array in the second dimension
