How big matrix that matlab can handle? In my project, the program may need to generate and operate on a matrix with size of 50000*5000, and each entry is a double value.

Hi,
it depends on version and operating system: on a 32Bit OS this will definetely fail, because the matrix would need about 1.8GB of memory. On a 64Bit machine (with reasonable new MATLAB release).
doc computer
shows the maximum number of elements allowed in an array.

On 32 bit Windows machines - still the most common platform - a practical size of matrices ends with about 500MB. Always remember that you need memory for the operation and simply loading is not enough.

You could look for ways to reduce your grid size. Are there symmetries you can take advantage of? Can you use a skewed or adaptive mesh? Do you NEED double precision?
