I am Trying to convert a MATLAB code to C++ using MATLAB coder but this error apears:

Error indenting generated C code

The error points to the name of the function itself and has no more explanations in it. can someone tell me what is this error? here is the function i want to conver:

function [Report_Clustered,ClusterCounter_new]=InitClusterGenerator_test(Report_In,~,FreqEpsilon,DegreeEpsilon,~,ClusterCounter_old, BlockCount, Report_old)

Report_M = zeros(size(Report_In,1),size(Report_In,2),4);
for i=1:size(Report_In,1)
    for j=1:size(Report_In,2)
        Report_M(i,j,1)=Report_In(i,j,1);
        Report_M(i,j,2)=Report_In(i,j,2);
        Report_M(i,j,3)=0; % Cluster number that the point belongs to.
        Report_M(i,j,4)=0;
Report_In{i,j} 
    end
end
ClusterCounter = 0;
for i=1:size(Report_M,1)
    for j=1:size(Report_M,2)
        if (Report_M(i,j,3) == 0)

Could you paste the exact error message with a small repro code? Also, which version of matlab are you using? –  Lokesh A. R. Feb 25 '14 at 11:54

Problem solved. this error must be something about the matlab not being able to overwrite the files built in the mex making process. you should quit matlab, delete the files made by coder and try running the coder again. ty @LokeshA.R. anyway. –  Brokenlink Feb 25 '14 at 12:17
    
Perhaps, you could add the solution too. It will help others who have the same error message. –  Lokesh A. R. Feb 25 '14 at 16:40
    
the solution is simple, the problem is when you build, say .mex file from your matlab code using coder and run it, when you want to make changes in the matlab code and build it again you may face this error. I think this situation only happens when your .mex code stops working with an error. I think MATLAB somehow do not closes the .mex file it is running so you can not rebuild it. in this situation if you try to delete the .mex file from workspace you would notice that it says permission is denied, so you just have to close matlab and delete .mex file and run matlab again. hope it's helpful. –  Brokenlink Feb 26 '14 at 7:34
    
@Brokenlink, thank you very much, I never could think this way –  Dmitry Galchinsky Apr 15 '14 at 17:22

From what you've said in the comments, it appears that you simply need to call 

clear functions

from the command line before recompiling the function to allow Matlab to overwrite the files. See this Matlab forum or the documentation for clear for more detail.
