replace the function "randperm" into code from embedded block SIMULINK
显示 更早的评论
hi, I need to generate a c code from the next code wrote on an embedded editor from embedded block from simulink, but randperm is not supported by code generation, is there some way to do it?
thanks for you support
Size = 100
n = 50
pop = zeros(Size,n);
pop(1,:) = (1:n);
for k = 2:popSize
pop(k,:) = randperm(n);
end

randperm() is actually:
[~, p] = sort(rand(1,n))
Does this work in code generation?
In the current Matlab version, randperm uses the smarter Fisher-Yates-Shuffle, when 2 inputs are used. Would a corresponding C-Mex function work: FEX: Shuffle ?

Another useful implementation of the Fisher-Yates-Shuffle in pure Matlab: http://www.mathworks.com/matlabcentral/fileexchange/30101-rpg-lab
