function phaseUpwrapper3 doesn't initailize variable 'ind_min' 'ind_second' before used

Hi, there！below is your code,i don't if i misunderstanding ,something seems to be wrong for vaviable 'int_min,ind_second',and what does it mean!
thank you for you time!

void phaseUnWrapper3(float t0, float t1,float t2, float* phase_first, float* phase_second, float* phase_third, float* err_w1, float* err_w2, float* err_w3)
{
float err;
float err1,err2,err3;

    float w1 = 1.0f;
    float w2 = 10.0f;
    float w3 = 1.0218f;

    float err_min=100000.0f;
    float err_min_second = 200000.0f;
    float err_min_third = 300000.0f;
    unsigned int ind_min, ind_second, ind_third;

    float k,n,m;

    for(int i=0; i<30; i++)
    {
	    m = m_list[i];
	    n = n_list[i];
	    k = k_list[i];
	    calcErr(k,n,m,t0,t1,t2,&err1,&err2,&err3);
	    err = w1*err1*err1+w2*err2*err2+w3*err3*err3;
	    if(err<err_min)
	    {
		    err_min_third = err_min_second;
		    ind_third = ind_second;
		    err_min_second = err_min;
		    ind_second = ind_min;
		    err_min = err;
		    ind_min = i;

	    }

I admit this piece of code is ugly. It is simply goes through all phase unwrapping hypotheses and rank the three with the lowest error. I guess you could instead loop through and compute all the errors and then sort them afterwards...
