Simple Solve command not working.
显示 更早的评论
My command:
solve('0.5 - 25/8 + 4*E = 0',E)
The error:
Warning: Explicit solution could not be found. > In solve at 83
ans =
[ empty sym ]
W...what? Is this a joke?

When you use solve with a string input, it interprets the "E" as exp(1). Try this:
solve('x = E', 'x')
If you really want to call your variable E, then remove the apostrophes:
syms E
solve(0.5 - 25/8 + 4*E == 0,E)
