I have a symfun like this:
>> p
p(t) =
[ 0, -(800*pi^2*exp(10*log((489*pi)/50 + 5*sin((11*pi)/250)) - 10*log(10*pi))*(9*cos((11*pi)/250) + (489*pi*sin((11*pi)/250))/500 - 5*cos((11*pi)/250)^2 - 4))/((489*pi)/50 + 5*sin((11*pi)/250))^2, -(800*pi^2*exp(10*log((239*pi)/25 + 5*sin((11*pi)/125)) - 10*log(10*pi))*(9*cos((11*pi)/125) + (239*pi*sin((11*pi)/125))/250 - 5*cos((11*pi)/125)^2 - 4))/((239*pi)/25 + 5*sin((11*pi)/125))^2, -(800*pi^2*exp(10*log((467*pi)/50 + 5*sin((33*pi)/250)) - 10*log(10*pi))*(9*cos((33*pi)/250) + (467*pi*sin((33*pi)/250))/500 - 5*cos((33*pi)/250)^2 - 4))/((467*pi)/50 + 5*sin((33*pi)/250))^2, -(800*pi^2*exp(10*log((228*pi)/25 + 5*sin((22*pi)/125)) - 10*log(10*pi))*(9*cos((22*pi)/125) + (114*pi*sin((22*pi)/125))/125 - 5*cos((22*pi)/125)^2 - 4))/((228*pi)/25 + 5*sin((22*pi)/125))^2, -(800*pi^2*exp(10*log((89*pi)/10 + 5*sin((11*pi)/50)) - 10*log(10*pi))*(9*cos((11*pi)/50) + (89*pi*sin((11*pi)/50))/100 - 5*cos((11*pi)/50)^2 - 4))/((89*pi)/10 + 5*sin((11*pi)/50))^2, -(800*pi^2*exp(10*log((217*pi)/25 + 5*sin((33*pi)/125)) - 10*log(10*pi))*(9*cos((33*pi)/125) + (217*pi*sin((33*pi)/125))/250 - 5*cos((33*pi)/125)^2 - 4))/((217*pi)/25 + 5*sin((33*pi)/125))^2, ...
but when I try to convert it to doule I get(this used to work fine in MATLAB 2018b)
>> pp=double(p)
Error using symengine
Unable to convert expression into double array.
