plotting the graph changing by the range
显示 更早的评论
the given equation is
n=~20
x(n+1)=1.4x(n) for 0<x<0.5
x(n+1)=1.4(1-x(n)) for 0.5<x<1
I tried to use 'if' and 'elseif', but I can't make it repeat.

x(1) = something
for n = 2 : number of iterations
if x(n) has some property
x(n+1) = some formula
elseif it has some other property
x(n+1) = some other formula
else
give an error because the situation is not defined
end
end

In MATLAB,
if 0<x(n)<0.5
means the same as
if ((0<x(n))<0.5)
The first test, 0<x(n) gives a logical result that is 0 (false) or 1 (true). Then the second test compares that 0 or 1 to 0.5. That code does not test to see if a variable is in a particular range. To test for a particular range, use seperate tests:
if 0 < x(n) & x(n) < 0.5
I should have written for
for n = 1 : 20-1
