Hi everyone,

I have an equation equal to zero, in this equation I have 'g' how is a vector I am tring to find.

my equation:

g(2:end)*s - g(1:end-1) == 0

s- is a known scalar

g- is a 100x1 vector that I want to find

I tired usying smys, smy and solve but couldn't solve what 'g' is.

Thanks in advance.

Your equation seems to be equivalent to

. You need an initial value to solve this equation.

g = zeros(1, 100);
g(1) = 10; % initial condition
s = 0.5
for i = 2:100
    g(i) = 1/s*g(i-1)
end

Or for this particular equation, following will also work

g = (1/s).^(0:99)*10
