I am very, very new to MATLAB, and can't seem to figure out this seemingly simple problem.

Given a t-array and a y-array for a decaying exponential function, my task is to find the first relative maximum in the graphwithoutusing Matlab's preset relative max. functions. I'm attempting to do this by comparing y-values at a certain "t" to y-values at "t0" and "t1" (before and after "t"). I'm using indexing, for loops, etc.

2. Relevant equations

N/A

3. The attempt at a solution

function[max,t_max] = relMax(t,y)

for i = 1:.001:length(t);

y(:,i+1) = y;

y0 = y(:,i);

y1 = y(:,i+2);

if (y0<y && y>y1)

max = y;

disp(max)

t_max = t;

disp(t)

break

end

end

---

Clearly I am making some kind of stupid mistake here. I don't really know how to use indexing very well, and it's causing me problems.

Thanks in advance!
