As shown in the command window there seems to be missing inputs within my function. Since you specifically asked for help on fzero , this works:. Sign in to comment. Your code suggests that you are trying to find s that satisfies the expression, but your text description indicates you need to find t? Function to solve, specified as a handle to a scalar-valued function or the name of such a function. Main Content. Input Arguments collapse all fun — Function to solve function handle function name. Nondefault Options. I need to use fzero to solve for s at different times, t. Any advice is welcome! Pass a function name, function handle, or a cell array of function names or handles. In this case, the search terminates when the search interval is expanded until an Inf , NaN , or complex value is found. This function fully supports thread-based environments. That is so informative and easy to understand!!! Answers Support MathWorks.

The value x returned by fzero is near a point where fun changes sign, or NaN if the search fails. In this case, the search terminates when the search interval is expanded until an Inf , NaN , or complex value is found. If x0 is a vector of length two, fzero assumes x0 is an interval where the sign of fun x0 1 differs from the sign of fun x0 2.

Note For the purposes of this command, zeros are considered to be points where the function actually crosses, not just touches, the x -axis. First, fzero finds roots of nonlinear functions and should not be symbolic. Root-finding problem, specified as a structure with all of the following fields. Reload the page to see its updated state.
