I need to create a Fibonacci sequence using the for loop function. the first two number of the Fibonacci sequence must be defined from a user input.
I then need to plot this on a polar graph with the element number as the angle and value of the element in the sequence for the radius

% Fibonacci sequence
clear;clc;
sequence_end=25; %Insert the Sequence end here
F_curr=zeros(1,sequence_end);
golden_ratio=zeros(1,sequence_end-1);
F_curr(1) = 0; %Insert First Value of the sequence here
F_curr(2) = 1; %Insert second Value of the sequence here
i=3;
golden_ratio(1)=F_curr(2)/F_curr(1);
for n=3:sequence_end
F_curr(i)=F_curr(i-1)+ F_curr(i-2);
golden_ratio(i-1)=F_curr(i)./F_curr(i-1);
i=i+1;
end
disp(F_curr)
disp(golden_ratio(end))

In the code you shared, you made a mistake in the line inside for loop. Despite that, your logic is correct. Correct it as follow,
s(i)=s(i-2)+s(i-1); % you missed second s

@dominic: READ THE HELP FOR POLAR PLOT! Before you use any function, read the help. Make sure you understand what the arguments are intended to mean.
polarplot(TH,R) plots vector TH vs R. The values in TH
are in radians.
Really, you were so close.
You were asked to plot: "with the element number as the angle and value of the element in the sequence for the radius"
What did you do?
polarplot(s,d)
You passed in the arguments in the wrong order.
You were told to use the element number as the angle (in radians). So do this:
polarplot(d,s)
So close, yet so far. :)

Try this one!!!
function a=FabonacciSequence(n)
a(1)=0;
a(2)=1;
for i=1:n;
a(i+2)=a(i+1)+a(i)
end
end

x = input('enter the first and second number of the sequence:')
y = input('enter the number of elements in the sequence:')
for k = 3:y
n(1) = x;
n(2) = x;
n(k) = n(k-1)+n(k-2);
end
n
polar(n)
