MATLAB: How to covert a Matlab struct 1×1 to C++ without an error

Question

Hi,

I tried to generate C++ from Matlab with the Matlab coder. But I always got an error.

The error is:

>> coder -build test_struct.prj ??? This structure does not have a field 'fs'.

Error in ==> gen_strucht Line: 3 Column: 15 Code generation failed: Open error report.

Here is the Matlab-Code:

 function [test_struct] = gen_strucht(test)
 test_struct.x=test.fs;
 test_struct.y=test.ts;
 test_struct.a=test.modfac;
 test_struct.q= test_struct.x * test_struct.a;
 end

So what can I do?

Thanks for help.

Have you already specified the input structure type in the project?
