How do i obtain results of a function I created by calling it from another script file.

function [] = mychaos(Initial_Value)
        x=Initial_Value;
        a=3.9;
        x=a*x*(1-x)
    
end

My call function is shown below.I would like to pass the x=0.4 to the function above and obatin a new x value.The new x value should be able to override the old x value used.How do I go about it with wrapping the x=a*x*(1-x) in a for loop?

x=0.4
for i= 1:20 ;
    mychaos(x)
end

Hi,

change your function to:

function x = mychaos(Initial_Value)
        x=Initial_Value;
        a=3.9;
        x=a*x*(1-x);   
end

and your call of the function:

x=0.4
for i= 1:20 ;
    x=mychaos(x)
end

This overwrites x twenty times with the result of your function, calculated using the actual value of x.

Best regards

Stephan
