Suppose if we have few 'if' statements and I want these to be executed in random order. For example, here are given five 'if' statements one for each row of a matrix. In random execution, any 'if' statement may execute first and similarly rest functions.
X is a random matrix of order 5*10
if any(X(1,:))
X([4 5],:)=0;
end
if any(X(2,:))
X(4,:)=0;
end
if any(X(3,:))
X(5,:)=0;
end
if any(X(4,:))
X(2,:)=0;
end
if any(X(5,:))
X([1 3],:)=0;
end

order_to_use = randperm(NumberOfConditions);
for idx = 1 : length(order_to_use)
switch order_to_use(idx)
case 1: if any(X(1,:)); X([4 5],:)=0; end
case 2: if any(X(2,:)); X(4,:)=0; end
...
end
end
