MATLAB 2007 Segmentation Error While Preforming Vector Appendaging

When running the following line of code, I get this Segmentation Error in MATLAB 2007B; Note that the OS is Genuine Windows 7 Pro:

%tick = count of instances where the evaluation vector occurs;
percentCalc = tick/numel(EvaluationVector)*100; 
percent(end+1)= percentCalc; %adds an additional element of percent "percentCalc" to the growing vector %I believe it crashes on this line and gives this dump message

Both percentCalc and tick are initially defined as 0, while percent is initially defined as empty (all vars defined before the code above). This is in a for loop.

This error occurs on two machines with the same setup, however, one of them skips the following Error Display and exits out of MATLAB:

Please follow these steps to report this problem to The MathWorks so we have the best chance of correcting it:

The next time MATLAB is launched under typical usage, a dialog box will open to help you send the error log to The MathWorks. Alternatively, you can send an e-mail to [e-mail] with the following file attached:

      C:\Users\NSPL308\AppData\Local\Temp\matlab_crash_dump.4984

If the problem is reproducible, please submit a Service Request via:
    http://www.mathworks.com/support/contact_us/ts/help_request_1.html

A technical support engineer might contact you with further information.

Thank you for your help. Save your workspace and restart MATLAB.

A. Any Ideas as to what is going on? Is this a java library issue? Am I invoking a method that doesn't exist? Or is the memory getting overloaded?

B. If you do know what is happening, are there any fixes I can do to my code or MATLAB (can't upgrade though) to remedy the situation?

[Midimistro]

Upon further testing, this seems to be a vector appendage (aka adding elements to a vector stability issue. I found a way to get around this error, but I have no need to display the results of the appendage.

Here the fix I came up with:

percent = [percent; percentCalc]

The problem, as mentioned earlier in the comment, is that I have no need to see the percent vector till the code has run its full course.

Any ideas?

[Ced]

Is there no way for you to know how often EvaluationVector will be changed? Do you save all the instances of EvaluationVector?

What happens if you do:

percent(end+1,1) = percentCalc;

?

[Midimistro]

Haven't tested the percent(end+1,1) yet, but the EvaluationVector is a predefined vector already in the default workspace, separate from anything generated by the script/function.

Regarding percent(end+1,1), what does the extra ",1" do?

[Ced]

If you do know the total length of percent a priori, you should preallocate it, e.g. percent = zeros(N_ticks_max,1);

The extra "1" does that your elements get appended in a column rather than in a row. Matlab prefers columns.

Answer 1

[Midimistro]

I found out a while back that the problem was actually the percent appending task. Sorry I didn't close the question earlier.

I found the following worked accordingly:

 percent(end+1,1)= percentCalc; %appends new value to percent. Works only with R20??+. Column vector format. Most likely introduced with graphical interface change. Faster.
 %or
 percent = [percent; percentCalc] %Legacy version of appending(works with R2007b+), column vector format. Slower.

I think it is a memory overflow issue that R2007a was not designed to handle, thus the need for different versions based on the version of MATLAB I use.

Thank you for the help though!
