Revision history [back]

I have a selfcompile sage, and adjusted Java Version on the system, so this is running fine in notebook():

x,y,z=var('x y z') plot_vector_field3d((xcos(z),-ycos(z),sin(z)), (x,0,pi), (y,0,pi), (z,0,pi),viewer='jmol')

But Jupyter notebook does not want to show vector field 3d: ....

Any help?

I have a selfcompile sage, self-compiled Sage, and adjusted Java Version on the system, so this is running fine in notebook():the SageNB notebook (obtained with notebook()):

x, y, z = var('x y z')
plot_vector_field3d((xcos(z),-ycos(z),sin(z)), (x,0,pi), (y,0,pi), (z,0,pi),viewer='jmol')
plot_vector_field3d((x*cos(z), -y*cos(z), sin(z)), (x, 0, pi), (y, 0, pi), (z, 0, pi), viewer='jmol')
