I am trying to find the time, t, at which the maximum value occurs at. The variable 'maxgiven' displays a 1x5 vector of the maximum values for a set of data. Trying to find the time, t, at which each maximum value is occuring at, which would be labeled 'tmaxgiven'. The test case written belows displays an empty vector. Please use the variable names provided.
maxgiven = [max(y1(:,1)); max(y2(:,1)); max(y3(:,1)); max(y4(:,1)); max(y5(:,1))]
%test case
tmaxgiven = find(t1 == max(y1(:,1)))

Ran in:
time=(1:5)';
val1=[10 13 45 23 11]';
val2=[56 23 45 89 23]';
val3=[90 78 12 45 22]';
matrix=[time val1 val2 val3]
matrix = 5×4
1 10 56 90 2 13 23 78 3 45 45 12 4 23 89 45 5 11 23 22
[M I]=max(matrix(:,2:end))
M = 1×3
45 89 90
I = 1×3
3 4 1
I is your time(row) index
