Hi all,

I use an FFT-block in Simulink to calculate the power spectrum. The Simulink module should be converted later by the embedded coder of Matlab into C source file. When I convert the module into C I have found that the embedded coder has generated a declaration of the FFT without a definition.

Could anybody please tell me how to overcome the problem here. I am using a Real-Time Workshop Embedded Coder v. 4.5, Matlab v. 7.3 (2006b) and Simulink v. 6.5.

Thank you in advance

Safwan

Not entirely sure, but this solution might be relevant to your case: Why do I receive an "unresolved external symbol" error during the linking stage when I try to compile generated code from DSP Blockset blocks?
