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) with best regards

[Numpy-discussion] feature tracking in numpy/scipy

2013-03-02 Thread Scott Collis
Good afternoon list, I am looking at feature tracking in a 2D numpy array, along the lines of Dixon and Wiener 1993 (for tracking precipitating storms) Identifying features based on threshold is quite trivial using ndimage.label b_fld=np.zeros(mygrid.fields['rain_rate_A']['data'].shape) rr=10 b
