generate y(n)=y(n-1)+x(n)

hello i want to generate y(n)=y(n-1)+x(n). by using a for loop I can find the last value of y, but i need to store all values of y from n =1 till n. Who do I do that?

Answer 1

[Azzi Abdelmalek]

n=10
y0=0; % Initial conditions  
y(1)=y0+x(1); 
for k=2:n
    y(k)=y(k-1)+x(k)
end

[Marwan Malaeb]

that is right, thanks Azzi.

Answer 2

[Roger Stafford]

That is precisely what the matlab ‘cumsum’ function does:

y = cumsum(x);

[Joshua Iascau]

you said what?

Answer 3

[polat kayhan]

𝑋𝑛+1 = 𝑋𝑛 2 + 0.25

Information about its relation, calculate the value of its relation for a value of n, register

Write a computer program whose result will be output for n = 0, 5, 10, 15,… communication only.

n = 0,1,2,3,…., 54

Answer 4

[Sanskriti]

n=10

y0=0; % Initial conditions

y(1)=y0+x(1);

for k=2:n

y(k)=y(k-1)+x(k)

end
