HELLO,

In main program I call two functions. I'm reading four big files in main program and the functions in total.

I recieved the following error message :

Error using dlmread

Out of memory.

Error in IC_realdata1 (line 18) %%%%FUNCTION

w=dlmread('we.txt');

Error in obj_realdata1 (line 30)%%%% FUNCTION

c=IC_realdata1(gen(ch,j));

Error in EXAMPLE_GA_TOUR (line 21)%%% THE MAIN PROGRAM

a=obj_realdata1(gen);

Answer 1

The message is clear: "Out of memory" means, that the size of the data, you try to load, exceeds the available RAM.

Install more RAM or clear data, which are not used anymore.

Another option is to use the big data functionality in MATLAB, which is designed to operate on data sets that are too large to fit in memory.
