Loading files to simulink coder in R2012b

Hello,

I met the same problem as described in http://www.mathworks.com/matlabcentral/answers/35906-loading-files-into-codegen-files.

However, i failed to compile it with the following error:

??? C function calls always return scalar values but a non-scalar value is expected here.

Is there anyone have successfully load files and get the variable in the coder?

Thanks.

Best,

Zhicheng
