Method Detail

validateArray

public static <T> T[][] validateArray(T[][] array)
                               throws MatrixException,
                                      NullPointerException

Validates if array is a well-formed array in terms of a matrix.

Well-formed arrays meet the following criteria:
- Both dimensions have a size greater than 0.
- No nested array may be null.
- All nested arrays have the same size.

Type Parameters:

T -

Parameters:

array -

Throws:

MatrixException

NullPointerException

getType
