Code won't run more then once correctly

When I run the code provided, it works, then when I try to run it again it doesn't go all the way through, spits out data and doesn't create the plots desired. I can clear all, clc and then it runs correctly but it doesn't work again. Please provide feedback when you get the chance. Thank You.

%%Shear Beam - Analysis
clear all
close all
clc
set(0,'DefaulttextFontName','Times New Roman')
set(0,'DefaultAxesFontName', 'Times New Roman')
set(0,'DefaultAxesFontSize',12)
set(0,'DefaultTextFontSize',14)
addpath(genpath('J:/Research/Testing'))
load PS_0SR_192_72_NC_V_data.txt; 

%%A. Data Location

data = PS_0SR_192_72_NC_V_data;
time = data(:,1);

m2 = (find(time==1176.021716));

What do you learn when you step through it line by line in the debugger? I bet that would tell you what lines of code it's executing and let you know what the problem is. You didn't attach PS_0SR_192_72_NC_V_data.txt so we can't run your code to test it - you have to do that.

I left an answer with the file attached. Thank you for your help.

I ran it several times. All times it produced 4 figures. It never failed to run.

[CPdaCE]

Hmm. Weird. Well thanks for you help.

In the line before

for i =1:3

change the hold on to hold off

[CPdaCE]

I tried doing that and it still will only run correctly after I clear all and close all in the command window. Thank you for the help.

Thank you for the speedy response. Here is the file that I used to build the plots and what not. And I have not tried/heard of the debugger I will try it out. Also, changing hold off did not fix the problem. Let me know if you guys figure anything else out. Thank you again.
