Having trouble with feval and function Asked 2 years, 11 months ago Modified 2 years, 11 months ago Viewed 197 times result = Feval(h,'functionName',numout,arg1,arg2,) executes MATLAB ® function functionName in the Automation server attached to h. I am only considering the use of feval in the context of What's your mental model for when to use the MATLAB function feval? Until Release 14 (MATLAB 7), feval was the way to evaluate a function handle. The way you used feval at that time was generally via a character array identifying the function to be called. To support backward compatibility, feval also accepts a function name string as a first argument. For example, the function: function plotf(fun,x) y = feval(fun,x); plot(x,y) can be used to graph This MATLAB function evaluates a function using its name or its handle, and using the input arguments x1,,xM. See syntax, description, examples and related functions. The number of output arguments, m, must not exceed the value of the To evaluate a nested or local function using feval, use a function handle instead of the function name. I have some understanding about anonymous functions and the feval function, but I searched the matlab docs and do not find an example using several @ signs. However, . g.
