I am using PDIST function of Statistics Toolbox to find
Euclidean Distance.
but the memory requirement goes beyond the RAM capacity when
I use matrix size (50000,20).

I am trying following :

a=randn(50000,20);
b=squareform(pdist(a));

How the memory requirement can be minimized?

By using smaller data sets. Just because
Matlab will allow you to type in any
expression, this does not mean that it
can then do the computation in the
memory you can provide.

I'm sorry, but there will always be things
beyond our reach. I'd like to visit the Moon
one day, but I'd likely not qualify to be an
astronaut. Learn your limits.
