MATLAB: Matlab Coder error in C++ code generation

cembedded matlab functionfunctionfunction handleMATLABmatlab codermexmex compiler

I am building a pairs trading module where I am using the following line pfun = @(x) pairsFun(x, DATA1, DATA2, annual Scaling, cost);

this is probably creating a function handle pfun to function pairsfun where the next line [~,param] = parameterSweep(pfun,range);

passes the function as argument to another function parametersweep which loops to find maximum value of a variable. The code is taken from matlab pairs trading module.

The issue is when I am trying to generate codes for C++ using coder the line pfun = @(x) pairsFun(x, DATA1, DATA2, annual Scaling, cost); is generating an error : this kind of expression is not supported.

It would great if someone provides some direction.

Anonymous functions are not supported for codegen. You will have to work around this by using a function handle to a regular function or sub-function.

Anonymous functions are not supported, but handles to actual functions are.

MATLAB: How to pass function handles to C++ mex function in MATLAB 7.8 (R2009a)

You can pass function handles to your C++ MEX files and then use “mexCallMatlab” function in C++ code to execute the function handles using the FEVAL command.

Please find the attached “simplefunction.cpp”, which takes two input arguments and returns an output. The types of input arguments are as follows:

a) A function handle

b) A double value

Please follow these steps to run the example:

1) Use the following command to select C++ compiler:

mex -setup

Please note that you have to choose one of the supported and compatible C++ compilers for your version of MATLAB.

2) Create the MEX file and pass the arguments

mex simplefunction.cpp
h = @cos;
x =0.6;
y = simplefunction(h,x);
