1. The problem statement, all variables and given/known data 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 graph without using 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!
Indexes must be integers. You should make your loop as for i = 1: length(t) 0.001 is the increment in t, not in the index.
