How can I fix an Out of Memory error?

Dear All,
I am running a quite large code on my university supercomputer, and I keep getting the following error:
Error using cat
Out of memory. Type HELP MEMORY for your options.
Could you help me please?
Thanks in advance.
Best regards,

Hello Hadi,
Mainly you're running out of RAM memory.
You may have to modify your code to be able to run it. There are different ways of optimizing the code.
1- Reducing the number of variables. for instance, instead of creating new variables, use the already defined variables.
x = y + 2; % x is a new variable can be avoided
y = y + 2; % there is no permanent x here however y value is changed
2- Define variables as single prevision single() or int32 or .... This is going to help a lot with big matrices! You just have to be careful if this is changing the precision of your process. (there is no point to assign a double to define a variable like 32, int is enough). This also may cause you some complications, as some operations only support double precision. (try this it's very effective)
3- Use sparse matrix if possible.
4- Close other applications that are using your PC's RAM.
These are all that I can think of. ATM
Good Luck!

Hi Hadi
One more point!!!!
You can clear the variables that you already processed and you don't need anymore.
x = y + 2;
clear y % assuming that you won't need y later.
