anyone can explain this error message

What does this message mean?

??? Error using ==> vertcat

Out of memory. Type HELP MEMORY for your options.

Answer 1

It means you don't have enough memory to do the operation and create the new variable. Did you type HELP MEMORY?

See the Mathworks suggestions: http://www.mathworks.com/help/matlab/memory.html

Answer 2

That error means that you have attempted to create a single variable that cannot fit contiguously into your system's memory.

Answer 3

[Brwa]

Thank you guys

yes, i typed but i couldnt understand it cleary, but Im clear with it now.

my problem is, I have a for loop which is extremely big 200,000,000 iteration and my RAM is 4G

is there any solution?

Image Analyst, I hope this time you think my for loop is big, hehe

Best regards

[Iain]

Do fewer iterations?

Write whatever you're logging to file? (Do this in chunks of a few 10MB at a time, rather than per-loop)

[Image Analyst]

It's not the fact that you're doing 200 million iterations, it's what you're doing inside it. And if you're concatenating something (who knows because you didn't provide code), then there is a possibility that that variable gets too big.
