Learn more about feval, code performance, best practices MATLAB The feval function enables an object to behave like a function in MATLAB ®. For feval, the Function_Information can be a function handle, or an inline object, or a symbolic function (not a symbolic expression), or a scalar string object, or a character row vector (or some curvefit In a blog post Loren states that up until Release 14 in 2004 you had to use feval to evaluate a function handle. The output from feval running a kernel on the GPU is always a gpuArray, even if all the inputs are stored in host memory. You can pass feval to another function that accepts a function input, such as For feval, the first argument can be a quoted string, giving you more flexibility than a function handle. 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. feval is useful in functions that accept string arguments specifying function names. The number of output arguments, m, must not exceed the value of the Note The preferred means of evaluating a function by reference is to use a function handle. result = feval ('', ) simply calculates the output of running the function with the name ' ' (as a Note The preferred means of evaluating a function by reference is to use a function handle. You can pass feval to another function that accepts a function input, such as This MATLAB function evaluates a function using its name or its handle, and using the input arguments x1,,xM. Each vector must have the same size. Use The MATLABLibrary::feval function allows you to call a packaged MATLAB function within a C++ shared library by passing the name of the function and its arguments. You can pass feval to another function that accepts a function input, such as The feval function enables an object to behave like a function in MATLAB ®. Learn how to use feval to evaluate a function at given arguments in MATLAB. You can pass feval to another function that accepts a function input, such as To evaluate a nested or local function using feval, use a function handle instead of the function name. You can pass feval to another function that accepts a function input, such This MATLAB function returns the predicted response of mdl to the input [Xnew1,Xnew2,,Xnewn].
