[Numpy-discussion] Building numpy on Windows 64-bit BLAS/LAPACK

2008-11-21 Thread Hanni Ali
Hi, I have spent some time trying to use different methods to build numpyon Windows 64bit with a version of BLAS/LAPACK other than the inbuilt one (no slur on the inbuilt one it is excellent, I am simply attempting to see if there is any alternative with better performance). The most recent i

[Numpy-discussion] working on multiple matrices of the same shape

2008-11-21 Thread Sébastien Barthélemy
Hello, I would like to port a matlab library which provides functions for rigid body mechanics such as operations on homogeneous matrices (in SE(3)), twists (in se(3)) and so. In matlab, the library worked on 3d matrices: n homoneous matrices were stacked along the 3d dimension. This speeded up

Re: [Numpy-discussion] numpy.ma.allclose bug

Charles, That should be fixed in r6087. In your example, the last statement outputs False instead of raising an exception. Note the deprecation warning: instead of fill_value, you want to use masked_equal to decide whether missing values should be considered True or False. Let me know how it

Look at numpy's savetxt and loadtxt. For more, look at loadmat and savemat in scipy.io Nadav -הודעה מקורית- מאת: [EMAIL PROTECTED] בשם Gideon Simpson נשלח: ו 21-נובמבר-08 23:35 אל: SciPy Users List; Discussion of Numerical Python נושא: [Numpy-discussion] MATLAB ASCII format Is
