MATLAB: Coder Cannot define entrypoint for classdef

Question

Im currently testing the matlab coder, sins we are looking to move our matlab projects into C for performance and integrating with a larger system. Most of our current codebase uses classdef's below is a simple example of what we are using.

classdef MeanAgent < handle
    properties
        d_Vec
        sName
        dEMA
    end
      methods
            function this = MeanAgent( sName  )
               this.sName = sName;
               this.dEMA = 0;
               this.d_Vec = [];
            end  
          function m = MeanOfNothing(this,dVal)
              this.d_Vec = [this.d_Vec dVal];
              m = mean(this.d_Vec);
          end
      end    
  end

When trying to generate code using the Coder, i get either stuck when asked to define input types, not being able to press next.

or im presented with the error:

matlab All entry-point files must be functions. MeanAgent.m is a class.

if i select "determin imputtype from codeprecondition.

Is the conversion just not possible, or how does the coder support classdef, i havnt managed to find this in any of your examples.

Answer 1

The entry point to MATLAB Coder must be a function. MATLAB classes are not supported as entry points. You can define a function that uses the MATLAB class and use it as an entry point.
