Python Pandas Timestamp Subtraction vs. Numpy -


i having odd issue when subtracting timestamps in pandas (version 15.2) on python 3.4

incorrect

y = pd.timestamp('2015-04-14 00:00:00') z = pd.timestamp('2015-04-14 00:01:01') np.timedelta64(z-y) >>>numpy.timedelta64(1000000,'us')

correct

w = np.datetime64(y) x = np.datetime64(z) np.timedelta64(x-w) >>>numpy.timedelta64(61000000,'us')

correct

y = np.datetime64('2015-04-14 00:00:00') z = np.datetime64('2015-04-14 00:01:01') np.timedelta64(z-y) >>>numpy.timedelta64(61,'s')

does have explanation?

seems issue pandas 0.15.2. upgrading 0.16.0 solves issue.

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
