When I start loading my text file I get this error how to resolve? the text file is attached. And I am getting this error :
Index in position 2 exceeds array bounds.
Error in damping (line 12) freq=dm(:,1);
close all
clear all
% LOAD DATA OBTAINED FROM FEA ANALYSIS load Sp.txt; dm= Sp; freq=dm(:,1); amp=dm(:,2);

My bet is that dm is empty which would imply either that your Sp.txt document is empty or it's not loading correctly.
dm = [];
dm(:,1)
Index in position 2 exceeds array bounds.

Step 1: understand what load() does and why that doesn't work with txt files. Please don't skip this step.
help load
Step 2: understand how dlmread() works.
help dlmread
Step 3: instead of using load(), use dlmread() with your txt file. I've tested it with your data and it works perfectly.

Mismatch between file and format character vector. Trouble reading 'Numeric' field from file (row number 1, field number 1) ==> ÿþ1 0 8 . 8 3 E - 0 5 \n
Error in damping (line 10) dlmread('Sp.txt');
I am getting this error when i use dlmread as:
dm = dlmread('Sp.txt'); freq=dm(:,1); amp=dm(:,2); figure(1)

This is weird. If I cut and paste your entire Sp.txt document into a new text file, the code works. But if I use your original file, it results in the error you shared.
I attached the identical copy-pasted file I used that works.
dm = dlmread('SpDanz.txt');

Thank you sooooooo much. May be when i converted data from excel file to txt file at that time i used a wrong .txt type. Thats why it was not working I used Unicode.txt. Thanku very much :)

Sorry, just noticed the content of the question now. The original file is in UTF 16 Little Endian encoding.
You can use my csv2table from This Posting . You will need both files I posted there.
