Using symbolic variables in matrix-multiplication with elements consisting of trig-functions I came across a symbol that I have not seen before. It shows up in two elements in the result:
38769523591\\\r\n65965*Dq3*sin(2*q2 + q3)
What is this mysterious operator ? I tried using vpa(), but still the operator got promped. However, using
the operator disappeared. I guess it has something to do with numerical accuracy in the symbolic math engine...
