Question: fsolve solutions

Question:fsolve solutions

PatD 20 Maple 16

Lately as my computations become ever more intense, I have been having trouble with fsolve. Why exactly does fsolve sometimes return itself as in:


returns--> fsolve({C1,C2,C3,C4},{c1,c2,c3,c4}}

and somtimes fsolve returns a blank.


What is going on internally here? Shouldn't it keep trying till it runs out of memory?
