how to resolve last funtion

[spinter]

well I expose th prblem I have a function that resolve the square root of a int on recursive mode , other funtion that says if a matrix is ssymmetric or not in a recursive mode, an the last function must say if the matrix of the square root of the elements is symmetric or not in a recursive mode too, i know i must use the 2 funtion before but always i have the same exception stack overflow i put here the code i have

package main;
