I have implemented a custom matrix printer with "_print_MatrixBase(self,
expr)." I am running "jupyter notebook" with the output of
"_print_MatrixBase(self, expr)" being given by -
def _print_MatrixBase(self, expr):
rows = expr.rows
cols = expr.cols
out_str = ' \\left [ \\begin{array}{' + (cols * 'c') + '} '
for row in range(rows):
for col in range(cols):
out_str += latex(expr[row,col]) + ' & '
out_str = out_str[:-2] + ' \\\\ '
out_str = out_str[:-4] + ' \\end{array}\\right ] '
if isinteractive():
return display(Math(out_str))
else:
return out_str
for "jupyter notebook" the output is "return display(Math(out_str))" where
the out_str ins the tex output for the matrix. The notebook output is -
see Capture.PNG
Where sp3.g is a sympy Matrix. Why is "None" output along with the
correct matrix output?
