How to fix this error in "for" loop?

Hi,

I need to find the Y value that corresponds to the maximum X value for the curves attached herewith.

I tried to use interp1, but I am not sure how to make it for several files.

I tried to develop this code, but it does not work.

I get the following error message:

Index in position 1 is invalid. Array indices must be positive integers or logical values.

Error in ResidualDisp (line 10)

maxy = matDrift(max(matDrift(:,1)),2);

The code:

clear; clc;
Folder = cd;
N=10;
for k = 1:N;
  Driftt  = sprintf('X%d.out', k);
  matDrift     = importdata(fullfile(Folder, Driftt));
maxy = matDrift(max(matDrift(:,1)),2);
end

Hi,

I think this expression, max(matDrift(:,1)),2 is not a non-zero integer. I would suggest you have a look into it since you are using it as an index.
