Really, most of what I do is element by element, punctuated by a few matrix multiplications (or whatever other matrix operations) at the end. If I had a penny for every '.' I put in front of an operator in MATLAB, I would buy us all new computers -- expensive ones even. I hope that, if there is another multiplication operator like .*, that this will be shorthand for dot(A, B), and not for elem-by-elem multiplication. -Rob Rob Hetland, Associate Professor Dept. of Oceanography, Texas AM University http://pong.tamu.edu/~rob phone: 979-458-0096, fax: 979-845-6331 - Using Tomcat but need to do more?

I was going to check in errstate, but it looks like Travis beat me to it, so I contented myself with adding a docstring and some tests. These tests are only run under 2.5; things seem to work fine here, but if someone on a Linux box whose running Python 2.5 could try it out I'd appreciate it. I'm suspicous of Linux/Windows differences right now because of my run in with them earlier today in the tests for test_multiarray (which I believe it now fixed -- at least everything is working here OK). -tim -- --- Using Tomcat but need to do more?

Re: [Numpy-discussion] Experience with Visit?
I have looked at it, and I even know somebody who is using python to put in a data reader for FVCOM (a finite volume ocean model). He has a prototype working. I have no experience with the python bindings personally. I looked into compiling it from source (for an intel mac), but it was daunting so I gave up. I also contacted them to try to put in lower level python bindings, so that we could create 3D graphics from the command line, but they didn't seem too interested in that. Otherwise, it is a very nice workable app. -Rob On Sep 15, 2006, at 11:23 AM, O'Keefe, Michael wrote: I haven't tried VisIT before but thanks for the link. I also downloaded and am checking it out.

Re: [Numpy-discussion] numpy-1.0b3 under windows
: --- python.exe - Application Error --- The exception unknown software exception (0xc029) occurred in the application at location 0x7c86d474. Click on OK to terminate the program Click on CANCEL to debug the program --- OK Cancel --- In the Python console it prints: -2147483648 If you can give me some idea of what should be happening, I can take a look at fixing it. When does the crash happen? Does it happen when you press Ctrl-C? What's supposed to be happening is that we are registering a handler for Ctrl-C that longjmps back to just after the code between NPY_SIGINT_ON and NPY_SIGINT_OFF. I'm not sure how to actually accomplish something like that under windows as I've heard mention that longjmp should not be used with signals under win32. The easy fix is to just define NPY_NO_SIGNAL in setup.py when on a platform that doesn't support using signals and longjmp (like apparently win32). If you could figure out what to do instead on windows that would be preferrable. -Travis -- --- Using Tomcat but need to do more? Need to support web services, security?
