source: branches/alma/src/python_STMath.cpp@ 1995

Last change on this file since 1995 was 1677, checked in by Takeshi Nakazato, 15 years ago

New Development: No

JIRA Issue: Yes CAS-1823

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed: The mode parameter is added to scantable.scale() method.

Test Programs: s = sd.scantable('yourfile',False)

factor = []
for i in range(s.nrow()):

factor.append(i)

s2 = s + factor

Put in Release Notes: Yes

Module(s): -

Description: Describe your changes here...

Basic operations (addition, subtraction, multiplication, division)
of scantable with one dimensional list are implemented.
Size of list operand should be equal to either number of spectral channel
or number of row. In the former case, the list is operated as
channel-by-channel manner, while it is operated as row-by-row manner
in the latter case.
If number of spectral channel is equal to number of row, row-by-row
operation will be done.

The user is able to select operation mode (channel-by-channel or row-by-row)
manually by using lower level function, stmath.arrayop().

The scantable.scale() method is updated to allow list scaling factor.
Scaling is done in channel-by-channel manner if mode is set to 'channel',
while in row-by-row manner if mode is set to 'row'.
