To support backward compatibility, feval also accepts a function name string as a first argument. I know that feval in general can cause issues when compiling, because required functions are determined only runtime. Character array passed as an argument to the feval function or an ode solver. Note it is not necessary to use feval to call a function by means of a function handle. Matlab compiler runtime is categorized as development tools. I can add some user specific data through a mat file, which is essentially a basic matlab file type used to store matlab variables and objects. Multiple a options are permitted if a file name is specified with a, the compiler looks for these files on the matlab path, so specifying the full path name is optional. The server returns output from the function in the cell array, result.
