Hi Brad,

I am not getting the attribute reshape for the array, are you having a different version of numpy than mine?

I have

In [55]: np.__version__

Out[55]: '1.7.0'

and detail of the shape

details of variable

In [57]: ssh??

Type: NetCDFVariable

String Form:<NetCDFVariable object at 0x492d3d8>

Namespace: Interactive

Length: 75

Docstring: NetCDF Variable

In [58]: ssh.shape

Out[58]: (75, 140, 180)

ssh??

Type: NetCDFVariable

String Form:<NetCDFVariable object at 0x492d3d8>

Namespace: Interactive

Length: 75

Docstring: NetCDF Variable

In [66]: ssh.shape

Out[66]: (75, 140, 180)

In [67]: ssh.reshape(75,140*180)

Hi all,
For a 3d array in matlab, I can do the below to reshape it before an eof analysis. Is there a way to do the same using numpy? Please help.

[nlat,nlon,ntim ]=size(ssh);
tssh=reshape(ssh,nlat*nlon,ntim);
and afterwards
eofout=[]
eofout=reshape(eof1,nlat,nlon,ntime)

Yes, easy:

nlat, nlon, ntim = ssh.shape

tssh = ssh.reshape(nlat*nlon, ntim, order='F')

and afterwards

eofout = eofl.reshape(nlat, nlon, ntim, order='F')

You probably want to go read through http://www.scipy.org/NumPy_for_Matlab_Users.

Cheers,

Brad
