High dimension matrix algebra

Hi there,
I'm trying to solve a set of linear equations by using Matlab syntax '\'. This properly works for dimensions less than 100000-by-100000. But for higher orders it starts to produce an error regarding the lack of enough memory and for dimensions greater than one million it says maximum variable size is exceeded.
Please help me to see how can I tackle this problem. I have a 10000000-by-10000000 set of equations to solve.

To store a 10000000-by-10000000 matrix you need 800TB Memory - assuming that it is full. As a rule of thumb the double size of free memory is recommended.
Do you see the problem?

That's what the sparse() command is for...so you don't have to allocate all the zeros occurring in your matrix.
