Whenever I run the file for the first time I get the error as:

??? Operands to the || and && operators must be convertible to logical scalar values.

Error in ==> fzero at 333
elseif ~isfinite(fx) || ~isreal(fx)

If fx is a matrix or vector, isreal and isfinite return matrices or vectors, with one element for each element of fx. However, the logical operators && and || need scalar values. Maybe you mean something like

~all(isfinite(fx)) || ~all(isreal(fx))

The function you passed to fzero, in combination with the initial parameters,
produced a multi-dimensional matrix of results instead of a single result (or
at most a vector of results, and the vector of results possibility is almost
certain to give you the wrong answer.)

Double check that in the function you pass to fzero, that you use element-wise
operations such as .* and .^ instead of matrix operations such as * and ^
