2016-02-27 08:55:33 +0200 | asked a question | Solving a system of equations using mpmath.findroot Hi All, A few weeks ago, the code below, which was designed to compute some points was working perfectly. After compiling it a few days ago, I got : ValueError: Could not find root within given tolerance. (7235.55 > 2.1684e-19) Try another starting point or tweak arguments. Please I will be very pleased if someone could help me solve this problem. Thanks for your understanding (more) |
2016-02-20 13:26:38 +0200 | asked a question | Export a VRML from SAGE and view the VRML file. I have a program that has as output a Polyhedra (3D object, Jmol.png is an image of it) in SAGE, and I needed to export the VRML file for further use. I used the right click to export the VRML file (a file such as exporting.png). When I opened the VRML file(extension .wrl), the resulting 3D image really different from the one produced by SAGE. Please how can I do to have a proper 3d object Similar to what appears in SAGE? Thank you in advance and have a nice weekend. |
