Inverse of a singular matrix?

I'm dealing with matrixes and I need to find inverse of them. But unfortunately Matlab has a warning for me.
Warning: Matrix is singular to working precision.
My matrix size are 25*25. It's diagonally dominant. I used "pinv" function however it's not so sufficient. It gives me true results partially. So I'm searching an alternative way to calculate inverse of these matrixes.
Do you have any alternative to "pinv" function?
Thanks and regards.

If the matrix is near to singular, a correctly computed inverse is not likely for numerical and mathematical reasons. Why do you assume that pinv is not sufficient?
The warning is equivalent to the reply of NaN when you divide a number by zero. And here it is also not the division, which is not sufficient, but the values.
