How can I multiply each bus element with a constant?

I created a Bus with more than 1000 Signals. Is there a way to multiply each element (or parts of the bus) with a constant without using a busselector?

This can be done easily with a ML Function block. Code in ML Fcn Block:

y = u; elemNames = fieldnames(u); for i=1:numel(elemNames) y.(elemNames{i}) = u.(elemNames{i})*2 + i; end

See atttached example.

Hi, thank you for your answer.

I use Matlab R2014b.

While running your example i receive this error: "Function 'fieldnames' is not supported for code generation. Consider adding coder.extrinsic('fieldnames') at the top of the function to bypass code generation."

But i have to generate code for a rtw application.
