Help required regding Eigenvectors
by Sudheer Phani 14 Mar '22

14 Mar '22

Hello All, I have been encountering some strange problems with the calculation of eigen vectors using python. The problem is with the sign of the eigen vectors calculated. On Very few occasions the eigen vectors calculated using python have an opposite sign than the actual eigenvectors, though the magnitude is correct. Can any one of you plz help me in this regard and suggest me some solution if you have encoutered similar problems . Any help in this regd is appreciated Thanks in Advace regds Sudheer

Units in SciPy
by Duncan Child 01 Apr '05

01 Apr '05

Hi all, We have been using the units package written by Michael Aivaziz which is available here: http://www.cacr.caltech.edu/projects/pyre/ http://www.cacr.caltech.edu/projects/pyre/epydoc/public/pyre.units-module.h… One potential issue is that a units package has to guess whether the user wants to convert a temperature gradient or a temperature: 1Celsius = 1Kelvin (gradient) 1Celsius = 274.15Kelvin (absolute) For a proprietary project Enthought reworked Michael's package to assume temperatures are absolute. This is maybe less surprising to a regular user but was tantamount to forking Michael's project. It also leaves the inherent ambiguity unresolved. If we put Mike's work into scipy we would probably want to use it unchanged. So my questions are: 1) any interest out there in us putting a units package into scipy? 2) any preference for a particular implementation? Unum, etc. 3) does anyone have input or suggestions regarding the temperature issue? Thanks, Duncan

bivariate spline

Hi, I was trying to use interpolate.bisplrep on a series of data points and I got the following error: numerix Numeric 23.0 iopt,kx,ky,m= 0 3 3 30 nxest,nyest,nmax= 9 9 9 lwrk1,lwrk2,kwrk= 1410 571 34 xb,xe,yb,ye= -9.68459276E-07 14.1335814 2.7324011 22.748873 eps,s 1.E-16 22.2540333 Traceback (most recent call last): File "relax_6.py", line 1001, in ? main() File "relax_6.py", line 976, in main bsp = bisplrep(x,y,h) File "/usr/lib/python2.3/site-packages/scipy/interpolate/fitpack.py", line 611, in bisplrep tx,ty,nxest,nyest,wrk,lwrk1,lwrk2) SystemError: error return without exception set x,y,h are all 1dim float arrays. I'm using a quite recent version of scipy from cvs and python 2.3 on linux. I'm a little confused about the usage of the bisplrep function. What type of input is allowed? I successfully tried with the rank-2 arrays output of mgrid[,] but with rank-1 arrays describing some points I get the error above. Are there different fortran subroutines being called depending on the input and is my type of input valid or did I misunderstand something? Regards, Christian

weave.inline keeps recompling my C++ code (fwd)
by Curtis Cooper 29 Mar '05

29 Mar '05

Hi, I'm using weave.inline to compare the performance of weave with several other methods of doing the same calculation. It is simply a matrix multiplication: Z = sin(X)*cos(Y). I have attached my program for you to peruse. I am in general very impressed with the usability and performance of weave. I have two questions, however: 1) Why does it tell me 'repairing catalog by removing key' every single time I run this program using 'python tryweave.py'? I thought the idea was for scipy-weave to only have to recompile the C++ portions if the C++ source code changes. 2) How can I use the sin and cos functions with weave.blitz? Up until now, I have had to comment out the weave_blitz version because I can't figure out how to add cmath support to my blitz++ expression. FYI, my system is Debian Linux (Sarge/Testing branch). The Python prompt says: Python 2.3.5 (#2, Feb 9 2005, 00:38:15) [GCC 3.3.5 (Debian 1:3.3.5-8)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> Cheers, Curtis

C/Fortran Integrate/minimization?
by Greg Novak 29 Mar '05

29 Mar '05

Some time ago I inquired about the ability to integrate a system of differential equations by specify a C function instead of a python function to compute derivatives. This speeds up the calculation enormously. There seemed to be interest in such a feature on the mailing list. I posted code to do this here: http://www.ucolick.org/~novak/integrate.tgz. Are there any plans to include such a feature in scipy? The issue comes up for me again because I'd like to do the same thing for function minimization. I have to do many fits as part of a computation and I suspect that the Python function call overhead is dominating the run time. Thanks, Greg

stopping criterion for integrate.odeint?
by Hans Fangohr 24 Mar '05

24 Mar '05

Dear all, we have been using odeint in a number of situations and it works great. Now we'd like to interrupt the integration of the set of ODEs once a conditions is fulfilled that depends on the solution that is being computed. Here is an example. Suppose we want to solve the ODEs associated with an object being thrown straight into the sky (i.e. against the gravitational force). Assume we can describe this by r''(t) = -g where r'' is the second derivative of the (scalar) position with respect to time. We convert this into two 1st order ODEs v' = -g and r' = v and use odeint to solve these. (So far, so good, please find attached below the complete program demonstrating this). Here is the complication: Assume we want to interrupt the integration if r<=0, e.g. when the object hits the ground. Is there an elegant way of doing this? The source code below should demonstrate what we try to do. A few more comments: (i) the actual example I am trying to solve is more complicated (yes, I can compute the time when the object hits the ground analytically in this case ;-) but that's not the point here) (ii) options I considered include: (a) integrating the set of ODEs in small steps dt by calling odeint repeatedly. Feasible but not beautiful as the final solution will depend on the size of this dt. (b) raising an exception in the rhs function (doesn't work) (c) setting all derivatives to zero in the rhs function (seems to do what I want since r and v don't change anymore, but is wasting CPU cycles because the integration doesn't stop). Okay, I hope I outlined by problem. Doe anyone have any advice? Many thanks, Hans ------------------------------------------------------------------------------------------------------------ import Numeric as N from scipy.integrate import odeint def rhs(y,t): """expect y = N.array([r,v]) Right-Hand-Side function to solve 2nd order ODE r''= -g (with g being a constant). returns dr/dt = v dv/dt = a = F/m = -g and """ r,v = y drdt = v dvdt = -9.81 #m/s^2 # this is what I don't know how to do elegantly if r<=0: print "We'd like to stop integrating now" return N.array([drdt,dvdt]) y = odeint(rhs, N.array([0,10]), N.arrayrange(0,3,0.1)) try: import pylab pylab.plot(y[:,0]) pylab.show() except ImportError: pass #can't import matplotlib

More Information - Build Error (Python 2.4, Scipy 0.3.2) on Windows XP
by Srijit Kumar Bhadra 24 Mar '05

24 Mar '05

Hello, Thanks to Brett for his reponse. I am now using MinGW-3.1.0-1.exe (gcc version 3.2.3 and not 3.3.3 as mentioned by Brett). I am still not sure whether the build is successful. Python crashed when I ran t=scipy.test() after installation of SciPy 0.3.2. So, I am copying and pasting, below, the last portion of build output(command python setup.py build --compiler=mingw32) in the dos window. After executing install command (python setup.py build --compiler=mingw32 install), I got errors which I am also copying and pasting, below.
