I have a problem in a function which manifest itself only at dealing with large numerical data. How I should post that numerical data, say a 100*100 real number array? Should I post the compressed text or should I link to an external site?

    Does it manifest only with that specific 100x100 matrix? Can RandomReal[1, {100, 100}] do or can you otherwise give the code to generate a representative matrix? If not, put it on a single line of code instead of breaking it up over several lines... this will also keep the post short visually.

(From R.M.'s comment)

If the question is not depending on a particular matrix (e.g. the error appears with any random matrix), then please use a concise, implicit one-line definition, for example:

RandomReal[{0, 1}, {100, 100}]

and omit the huge numerical representation.

SeedRandom can be used to make the results reproducible.
