Hello, so I have a nonlinear equation which is actually in the form of an array of values called y, and i would like to finde the zeros of this array so I am usigin fsolve but i got the error :
Error using lsqfcnchk (line 108)
FUN must be a function, a valid character vector expression, or an inline function object.
So I understand the problem is that y is a simple array of values but there is a way I can find the solution of this array i.e I can plot the array with plot(x,y) and I want to find the intersection with the y = 0 axis , is this possible ?

If you want o find the intersection, you can use this: https://in.mathworks.com/matlabcentral/fileexchange/22441-curve-intersections
You can pick the minimum using min.
