MATLAB: Made a code in matlab which includes functions like rand, eig, cov and many more. I want to convert the same to HDL, but cannot due to those functions.

HDL Coderhdl convertermatlab function

hello, Can anyone tell me how to find out eigen values and eigen vectors of large matrix of order 10×10 or more, without using the function 'eig', so that it becomes convertible to HDL using HDL converter?

10x10 is not a large problem. :) In fact, 10 is pretty small. That does not mean it is trivial for any general matrix, and the simplest solution may depend on some characteristics of your matrix. Is it real and symmetric for example? Is it positive definite?

You can reduce an eigenvalue computation into one of finding the roots of a polynomial. Or you can use the power method on some matrices. (Be careful if an eigenvalue has degree greater than 1, etc.)

And tools like cov are easily written as not much more than subtracting a mean followed by a matrix multiplication.

That should not be a problem. When you ask to process your top-level function, the coder will automatically find the routines that are called, and the routines that they call, and so on.

If you were using MATLAB Compiler instead of the HDL Coder, then the MATLAB Compiler tool would not always be able to find all referenced routines: it cannot automatically find routines that executed by eval() or evalc() or feval() on a string, or file handles created by str2func(). An case where the routine to be executed is determined at execution time by constructing the routine name from a string cannot be handled automatically by MATLAB Compiler. The %#function pragma is used to give "hints" to the MATLAB Compiler in such cases.

For HDL Coder, it seems to me that none of those methods of dynamic execution are supported anyhow, so this should not be a factor. But still, if you have a function being referred to that is not "obvious" then adding %#function pragma would not hurt.
