How do I apply a tolerance to my code

Outline

The singularityTest function will test whether a matrix is singular (i.e., not invertible). If it is singular, the output should be 1. Otherwise, the output should be 0. The input, A, can be any n × n matrix.

Your code needs to take into consideration very small errors that could occur due to floating point arithmetic (apply a tolerance of 10-10).

This is my code

function result = singularityTest(A)
   if det(A)== 0 
      result = 1;
   else
      result = 0;
   end
end
