I have a raster matrix with float values. I would like to find the minimum, median, mean, and the maximum values of my data, but when I use minA=min(A) I am receiving -1.797693134862316e+308 what represent the pixels with no data. How to exclude this value from my evaluation?

Reassign bogus values to something else, like 0 or infinity or nan. Make sure it's some value that won't also mess up your max calculation:
A(A<0) = 0;
minA = min(A(:));
