I have a question to ask, my input is 4 images mixed 4x200000 matrix and a 4x4 matrix, to do matrix multiplication. It told me "HDL Code generation does not support 2D-matrices as function inputs." How can I change it?

The only current way to do this is by implementing your own matrix multiplication. You will need 200000 * 4 * 4 = 3200000 multiplications to compute this matrix product, so I would not suggest a fully parallel approach. You could use the HDL multiply-accumulate block or the dot product block to compute each output value, and implement selection logic to feed the single-pixel compute core the correct set of vector inputs from your data source.

Is your code written in MATLAB, or are you using Simulink? If you are using Simulink then there are blocks you can call to serialize and deserialize; in particular there is the Vision HDL blocks .

My code is written in Matlab,can I not use blocks? Because I do not quite understand that teaching website, its block image is very vague.Currently I am having problems in this section, "set target interface".
