I have a 99 X 99 Matrix object that I populated from a 99X99 array of doubles. When I use the print method on the object I get several rows and columns of the ? character throughout the output. The program doesn't throw any exceptions. 

double myArray[][] = new myArray[99][99];
// Init the matrix...
Jama.Matrix foo = new Jama.Matrix(myArray);
foo.print(8,6)

Here is row 7, all 99 columns:

    I ran your code (with a couple changes to make it compile: changed your array declaration to `new double[99][99]` and ended `foo.print(8, 6)` with a semicolon), and it runs fine for me. All 0s, no `?`. – azurefrog Apr 14 '16 at 22:00

    I think this is an issue with your IDE output. It must be truncating or messing with it. Test with a lower window like `new double[10][10];`. – Tunaki Apr 14 '16 at 22:01

    That's the same version I grabbed. I'm agreeing with @Tunaki that this is an output issue, not a jama issue. – azurefrog Apr 14 '16 at 22:07
  • I think you're right. Thanks. – nicomp Apr 14 '16 at 22:17

Answer: The matrix contained NaN in many of the cells. Those 'values' were printing as the ? character.
