numpy with pip?

sudo apt-get install python-pip
sudo apt-get install python-dev    # after prompting from the following
sudo pip install numpy
sudo pip install scipy

Seems to be working on Chaos...  Ah, numpy was ok.  Scipy fell over due to lack of BLAS.

sudo apt-get install python-scipy

got it in there; presumably without BLAS setup.

pandas notes

Extracting f0

x = store['spl20130409_107-6']
f0 = x.Freq[(x.SPL == max(x.SPL))]

:)

Extracting a results set by frequency range and node number from a store object (a dataFrame)

storeName = root + '20121205-WEEaxisymConstDispSettleTimes.h5'

store = pd.HDFStore(storeName)
x = store['ball70_p']
f = x.Freq[(x.Node == 32) & (x.Freq > fmin) & (x.Freq < fmax)].values
p = abs(x.Pressure[(x.Node == 32) & (x.Freq > fmin) & (x.Freq < fmax)]).values
store.close()

My observations suggest the store is volatile:  it should be closed when not in use to prevent database failure in case of, say,
power failure.  So it seems an open and close should be used in each ipython cell.  Wrap with, the open and close functions.

This seems clunky.  :(


Creating a dataFrame with column based data and appending new results without new columns,  with sort based on one of the columns.


for i in [4]:
    a = mfile.File(root2 + '1_hw%i.O07' % i); a.load()
    b = pd.DataFrame(a.pressures, columns = ['Freq', 'Node', 'Pressure'])
    c = store['v22_1_p'].append(b)
    c = c.sort_index(by = 'Freq')
    store['v22_1_p'] = c


Creating a multicolumn dataFrame with labels.


b = pd.DataFrame(array([x0[0, 1:], x0[1, 1:], x0[2, 1:], x0[3, 1:], x0[4, 1:]]).transpose(), 
        columns = ['Time', 'pNode4', 'pNode31', 'pNode32', 'pNode11', 'dNode35'])



Deleting an item in the store:

store.remove(keyName)

Adding a column to a dataFrame: (this does not work with the store)

b = pd.DataFrame(Q, columns = ['f0', 'DisplacementAtF0', 'Q'])  # create
b['newCol'] = listVariable   # append column



Printing a whole dataframe or specific columns
