hi im new to matlab and just been doing some coding
but i was wondering if anyone could help me cause i really cant find how the code the delayed diescrete signal
so im trying to code the next signal
y[nT]=y[(n-1)T]+3x[nT]
and i tried coding it like
y = @(n,T) y(n-1,T)+3*x(n,T)
but i just cant plot the y[nT] using stem()
it just comes out as a blank so i thought there be an error in the code for the delayed part of y
could anybody help?

You need to initialise the sequence with some values. Looking at the documentation of stem() might help you understand better.

You need to have array x and initial value of y in hand first.
Example:
x = rand(100,1) ;
y0 = rand ;
n = length(x) ;
y = zeros(n,1) ;
y(1) = y0 ;
for i = 2:n
y(i)=y(i-1)+3*x(i) ;
end
stem(1:n,y)
