# Why covariation matrix is recorded with only lower diagonal part

Hello. I understand that the covariation matrix is symmetric but is there any way to print not only the lower diagonal part of it when I use Calc statistics? I need that matrix for my evaluations and I have to compute for example product A * x, where A is my covariation matrix and x - some vector but LibreOffice doesn't permit to produce that operation with matrix which is not recorded like m * n table.

Would you mind to tell us what function / formula you used to calculate / output the "covariation matrix"?

Neither my (incomplete) knowledge of statistics nor

en.wikipedia.orgnorreference.wolfram.comare mentioning such a thing, OpenFormula and LibO help not to talk of.Did you probably mean a "correlation matrix"? A "covariance marix"?

@Lupp There is information here

@peterwt: I knew that page. Thanks nonetheless.

Did you find something about "covariation" or do you assume (as I did) "covariance" was meant most likely?

Do you have an idea what formula / tool was used to create the triangular matrix?

There is no standard function for the purpose as far as I can see and the only statistical extension I found is old and "version 0.0." Of course, we may use COVAR once per a pair of n variables, but he who does it is responsible for the arrangement then.
