You need to define your MATLAB code as a function (it appears what you have now is a script). See Basic Parts of a Program File. You need to use the function keyword and specify any input/output arguments along with the function name.

Hello, i've gotta the some problem, but in other conversion type. I'm trying to convert a floating point code to fixed point format code. For that, i'm using a Test Bench Code, just like the tutorial below suggests.

http://www.mathworks.com/help/hdlcoder/examples/floating-point-to-fixed-point-workflow.html

The same error happens: the Builder sees the .m file of the testbench as a script. Although, i can't use it as a function because it would contradict the tutorial above. What should I do?

Hi Arthur,

Can you try making the script into a void void function (a function with no inputs or outputs)?

If you can send me your code I can give more concrete answer. (<mailto:[e-mail] [e-mail]>)
