I found the following example here.
@interact
def _(m=('matrix', identity_matrix(2))):
print m.eigenvalues()Unlike the other examples I've tried, this one does not work when evaluated in SageMathCell. But it works well in a SageMathCloud Worksheet.
What am I supposed to do to produce such a matrix interact that works when I embed it in html pages?
I just tried this more or less from the documentation and it worked on the cell server.
@interact
def _(m = input_grid(2,2, default = [[1,7],[3,4]], label='M=', to_value=matrix)):
print m
print m.eigenvalues()thanks a lot.
No problem; hopefully this will be fixed on the cell server within a couple weeks and it won't be an issue but it's nice to have this in a few places anyway.
Converting matrix to list and converting this list back to matrix by setting type=matrix is not straightforward but it works in sage cell server:
@interact
def _(m=input_box(list(identity_matrix(2)),type=matrix)):
print type(m)
print m
print m.eigenvalues()It works, thanks. Do you know how to use input_grid in this context?
input_gridis the canonical thing; the shortcut "u = matrix - an input_grid with to_value set to matrix.parent() and default values given by the matrix" from http://doc.sagemath.org/html/en/refer... is supposed to work.
See my answer.

Note: it also works in the Sage notebook; this is somehow a relatively new bug in the cell server.
