covariance matrix [message #91809]

Hello all

I have filled my missing value with NAN

data = Array[4176, 168]

ntime= 168

I am interested in calculating covariance matrix

matrix = (1/ntime-1) * (Double(data) ## Transpose(data))

I found this result

result = Array[168, 168]
Min = NaN
Max = NaN

Any help would be appreciate on how to do the covariance matrix on the good data with exclusion of missing data

Best regards
