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

HDL Codermatlab functionmatlabr2013a

Hello, I'm working on a project 'PCA' which deals with large valued random matrix, currently I'm dealing with 10×5 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.

You might find dynamic field names useful. Doc says:

    Generate Field Names from Variables
    [...] 
    For example, create a field name from the current date:
    currentDate = datestr(now,'mmmdd');
    myStruct.(currentDate) = [1,2,3]

None of those three functions are supported by HDL Coder, as you seem aware. Think about what you are trying to accomplish; are you really wanting to implement a random number generator in your FPGA? Perhaps the call to rand() can exist inside your testbench, and the data from it can be an input to your hardware design.

For involved matrix calculations such as eig(|) and |cov(), you will need to decompose these to the underlying algorithm. This is certainly doable, if a bit involved, and will be supported by HDL Coder. Since you are working with a fixed size array, you have the chance to optimize your implementation for the sizes involved, should the opportunity arise.
