Is there any alternative to this code?
v = find_system(model,'BlockType','Constant')
for k = 1:length(v)
set_param(v{k},'Value','0')
end
I'm working with a very large model and this code is very inefficient (more than 1 hour).
I would like to avoid the use of the for-loop, setting all the values at the same time. Is it possible?

The only alternative that I am aware of is using arrayfun like so:
arrayfun(@(x) set_param(v, 'Value', '0'), v)
However, arrayfun is slower than a for loop (see https://www.mathworks.com/matlabcentral/answers/42335-array-cellfun-vs-for-loop).
