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; diff(f)
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?
