I tried saving them as I usually do.. Either by Control+S or by going for "Save" or "Save As" options. Even quitting kernel was of no help. Interestingly, I am able to save the files in any other folder with different names, which is very...
Thanks a lot !! I agree with you, but not able to understand the reason behind the strange behavior of transformation matrix / Mathematica. I also confirmed the transformation matrix for any possible error by transforming general vector {a, b, c}...
Thanks. I will try this, but why the surface is not continuous here. Would prefer a continuous surface with a blur transition of colors, as is the case with density plots.
Thanks a lot Neil, appreciate your help. I was trying to "Throw" Break[] from k loop to m loop instead of "done", perhaps the reason why it was not working. The only reason for insisting on "Do" is that I have already invested few months to write...
Hi, I want to find out the section of a sphere remaining after putting constraints in terms of cartesian planes. How it can be done ? For example, if I have a sphere of r = 1, and I put the constraint z > 0 on it, simple imagination would...
I tried using `Rationalize[Inverse[Matrix]]`, but it did not work. Perhaps I am missing something. Can you please elaborate further. Following is the simplified example of my matrix, and I am facing problem while calculating its inverse E=...
Dear Sjoerd, I am still struggling with this code, not working the way it should, for 4 core computer. I tried many things in between, but nothing seems to be working. Will appreciate if you can spare some time and have a piece of advice on this....
Dear Friends, I have to use some complicated mathematical equations from a previous publication in my Mathematica notebook. These equations are available on science direct webpage in MathJax format, but I am not able to copy them as such. Also, I...
Dear Friends, I am struggling with a minor looking problem and could not figure out a solution. Looking forward for any help. Attached is the *.nb file containing my code. Followings are the important points 1. In the beginning of the code I...
Thanks for the suggestion. Would this problem be there even if I am doing "Quit Kernel" ? As you suggested, I included Clear[m, k], deleted all o/p and did "Quit Kernel", but problem persists !! Please have a look at atached file. Thanks
