Question: I did not call evalhf command, but receive an error about it, why?


In part of my program I defined variable Delta bar(`#mover(mi("Δ"),mo("-"))`), and used it and other parameters in a matrix named K (K=f(Delta_bar, x,y,...) then by using some mathematical operations, I initialled parameters to get my matrix named K.

Now I want to convert datatype of my matrix K with following command

M := Matrix(`~`[convert](K, float[8]), datatype = float[8]):

but receive following error:

Error, (in `convert/float`[8]) cannot handle unevaluated name ``#mover(mi("Δ"),mo("&uminus0;"))`` in evalhf

Do anyone know where the problem is?
