### Test Suite

Test Status Code Input and Output
1   Pass
HY = 2014; HV = 1270; wt = 0.5; CV_corr = 1270; assert(abs(gold_silver_weighted_standard(HY,HV,wt)-CV_corr)<5e-2)

2   Fail
HY = 500; HV = 50; wt = 0.5; CV_corr = NaN; assert(isnan(gold_silver_weighted_standard(HY,HV,wt)))

Array indices must be positive integers or logical values. Error in gold_silver_weighted_standard (line 7) N=HV/GV(HY-1790); Error in Test2 (line 2) assert(isnan(gold_silver_weighted_standard(HY,HV,wt)))

3   Fail
HY = 2500; HV = 5000; wt = 0.5; CV_corr = NaN; assert(isnan(gold_silver_weighted_standard(HY,HV,wt)))

Index exceeds the number of array elements (224). Error in gold_silver_weighted_standard (line 7) N=HV/GV(HY-1790); Error in Test3 (line 2) assert(isnan(gold_silver_weighted_standard(HY,HV,wt)))
