btw, if I use eml.extrinsic to execute it, I understand that the operation is performed externally, but, it affect my code when this is done?
replace the function "randperm" into code from embedded block SIMULINK

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
