How to display a RGB image (MFISH)?
by jp 02 Apr '23

02 Apr '23

Hi, I have written a script to try to combine five images into a three channels RGB images<http://dip4fish.blogspot.com/2011/05/trying-to-combine-mfish-images-into-rg…> . The resulting RGB image looks like a grey scale image instead of a color one. I have three np.array Rnorm, Gnorm, Bnorm which are copied into a rgb array: *rgb = np.zeros((shape[0],shape[1],3),dtype=float) mxr=np.max(R) mxg=np.max(G) mxb=np.max(B) Rnorm=np.uint8((255*(R/mxr)))Gnorm=np.uint8((255*(R/mxg)))Bnorm=np.uint8((255*(R/mxb)))#copy each RGB component in an RGB array rgb[:,:,0]=Rnorm rgb[:,:,1]=Gnorm rgb[:,:,2]=Bnorm* *pylab.subplot(224, aspect='equal',frameon=False, xticks=[], yticks=[]) pylab.imshow(rgb) pylab.show()* Any advice? Thank you Jean-Patrick

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

NumPy 1.20.0rc2 released
by Charles R Harris 24 Dec '20

24 Dec '20

Hi All, On behalf of the NumPy team I am pleased to announce the release of NumPy 1.20.0rc2. This NumPy release is the largest to date, containing some 670 merged pull requests contributed by 184 people. See the list of highlights below. The Python versions supported for this release are 3.7-3.9, support for Python 3.6 has been dropped. Wheels can be downloaded from PyPI <https://pypi.org/project/numpy/1.20.0rc2/>; source archives, release notes, and wheel hashes are available on Github <https://github.com/numpy/numpy/releases/tag/v1.20.0rc2>. Linux users will need pip >= 0.19.3 in order to install manylinux2010 and manylinux2014 wheels. *Highlights* - Annotations for NumPy functions. This work is ongoing and improvements can be expected pending feedback from users. - Wider use of SIMD to increase execution speed of ufuncs. Much work has been done in introducing universal functions that will ease use of modern features across different hardware platforms. This work is ongoing. - Preliminary work in changing the dtype and casting implementations in order to provide an easier path to extending dtypes. This work is ongoing but enough has been done to allow experimentation and feedback. - Extensive documentation improvements comprising some 185 PR merges. This work is ongoing and part of the larger project to improve NumPy's online presence and usefulness to new users. - Further cleanups related to removing Python 2.7. This improves code readability and removes technical debt. - Preliminary support for the upcoming Cython 3.0. *Contributors* A total of 184 people contributed to this release.

Help coding some math i have little understanding of
by Schuldei, Andreas 06 Dec '20

06 Dec '20

I want to 3d plot the magnetic field of a twisted three phase cable, and found a paper giving the analytical solution of the field like <https://imgur.com/a/WeNuveE> this<https://imgur.com/a/WeNuveE#9aelprK>. There are more details in the paper, of course. Now I dont feel confident with this kind of math. Where can i find someone willing to help me with this? Its research in university, no coorporation involved. I would need help writing code representing these equations in python, calculating the field`s vecors in one point r, phi. I dont ask that you do the work for me, I am not dense either. its just that i dont even know where to start with this math. Who ever wants to have a look at the whole paper for further details, it is <https://drive.google.com/file/d/1CuXA0Elgw1RsjzLpO7YQ9gDgF41_ToHT/view?usp=…> <https://drive.google.com/file/d/1CuXA0Elgw1RsjzLpO7YQ9gDgF41_ToHT/view?usp=…> .
