It should be noted that fzero is incapable of calculating zeros that merely touch the x-axis instead of crossing it Furthermore, fzero freaks out when it runs into an interval with an asymptote (Inf) or non a number (NaN). To quote: "The function values at the interval endpoints must differ in sign" and "Exiting fzero: aborting search for an interval containing a sign changebecause NaN or Inf function value encountered during search."
