I have tried the Octave (matlab-like) kernel in Sagemathcloud, but when I intended to perform the symbolic calculation in Octave, something strange happened, and I can't solve it.

My code is as follows:

pkg load symbolic
syms x
f = sin(x)^2;

when I execute it, error happened, it said

'ascii' codec can't encode character u'\u22c5' in position 13: ordinal not in range(128)

How can I solve this problem?

  1. If you don't have to use Jupyter, you can create a Sage worksheet (file ending in .sagews), then put %octave at the top of a cell, and your example works. For example:

  2. I've reported your bug to the Octave jupyter kernel issue tracker:
