MATLAB: Calculate an expression in MAtlab

MATLAB

(Sorry i don't know a better title)

I have

(n=0,1,2,3,….)

How can I calculate the below expression with matlab codes ?

Thank you

It depends on what ‘T’ and ‘c’ are.

If they are scalars, this would likely work:

T = rand;
c = rand;
x(1) = rand;
N = 10;
for k = 1:N
    x(k+1) = x(k)*T+c;
end

   for k=1:length(x)-1
       if  x(k)>=0 & x(k)<mu     
           x(k+1)=x(k)/mu 
       elseif x(k)>=mu & x(k)<0.5 
           x(k+1)=(x(k)-mu)/(0.5-mu)
       elseif x(k)>=0.5 & x(k)<1 
           x(k+1)=(1-x(k))/mu
       end
   end

MATLAB: How to create a vector with for loop

Hamzah - on each subsequent iteration of your loop, you are overwriting the data from the previous iteration since you are setting vt to something new. You need to concatenate the new data with the previous data so that you don't lose anything. Try the following:

x = [1,4,-1,5,0,2];
vt = [];
for k=2:length(x)
    if x(k) > x(k-1)
        vt = [vt x(k-1):0.1:x(k)];
    else
        vt = [vt x(k-1):-0.1:x(k)];
    end
end
