Error while using HDL coder

Hi All,

I am a postgraduate student who is working on a networking project, where I am trying to convert my code with HDL-coder to c from MATLAB also I have installed minGW w64 c/c++ compiler as ad-on

There were issues while using hdl-coder , once after resolving all conflicts getting the below error which I have no idea from where it is getting generated.

Could anybody guide/help me here.

The method STRING does not support multiple nodes. Use STRINGS instead.

Error in emlcprivate at 0

That sounds to me as if you are passing in a non-scalar string to something that expects a scalar string.

Thanks for sharing the reproduction steps.

Classes in MATLAB are not supported for fixed-point conversion. The cryptic error about unsupported construct (property validator) is a bug and is being resolved.

Thank you so much , By removing classes the earlier error got removed. But now hitting a new one.

seems like both a and b in b = pow2(a,K) are fi.

Error: POW2(A) is not supported when A is a FI object.

Could you please share if you have some thoughts on this.

Can you share your reproduction steps? It will help with the investigation.

• Design.m <algorithm you are trying to convert to C/HDL>
• Testbench.m <Calling Design function>
• Project.prj <Code generation settings and setup file>

Thanks

Hi , Attaching the file below. Trans.m is the starting code and Coordinator() is the invoking method.
