for (int i= 0; i < matrix.length; i++)
for (int j= 0; j < matrix.length; j++) // assume a square matrix
if (i != j && matrix[i][j] != 0) return false;
return true;
what is the if condition for return true ??

Wow, I should have looked up the definition of diagnol matrix and brush on my algebra, I was going by my own made up definition based on how I intrepreted your post. I am really sorry for misleading you. Regards

Please try again because your question doesn't make any sense (and it is a runon sentense). b.t.w. there is no condition that returns true; if all the matrix elements are tested the matrix is a diagonal matrix and you can simply return true; no condition needed.
kind regards,
