Is it necessary to declare functions and function calling in matlab code for hdl conversion?

Hello, I'm working on a project 'PCA' which deals with large valued random matrix, currently I'm dealing with 10x5 random matrix. I'v used simple matlab functions like eig, rand and likewise, but didnot include any function declaration and function calling. And also I'm unable to convert my code in vhdl through hdl coder.

As far as I recall, HDL Coder will refuse to compile a script as the main object. You must put a function header on the script in order to make it the entry point.

Thank you sir

Walter is correct. HDL Coder uses the design function interface to define the number and types of the hardware input and output ports.
