Description

• 

The findsym(M) function finds symbolic variables in M. The sequence of symbols are returned in alphabetical order.

• 

The findsym(M,n) function finds the n symbolic variables in an expression nearest in alphabetical order to the letter x.

• 

Symbolic constants like the imaginary unit and Pi are not considered variables, so they will not be returned from a call to findsym even when present in the given expression.
