The code I type is:
evalin(symengine,... ['numeric::solve(tan(pi*x/180)'... '+tan(((4000-2672)/2672)*pi*x/180)==626/(1300))'])
I get the answer:
ans =
[x == 17.971555160137556933421078470028]
I type:
I get the answer:
Error in MuPAD command: DOUBLE cannot convert the input expression into a double array.
If the input expression contains a symbolic variable, use the VPA function instead.
Error in sym/double (line 710) Xstr = mupadmex('symobj::double', S.s, 0);
