			This widget allows to manage '''"pseudo correlation"''' or '''covariance''' matrices.

			Why '''"pseudo correlation"''' ? In fact a real correlation matrix has its diagonal only with values of "1", the sigma values being given independantly. Here, we will consider a '''"pseudo correlation"''' with the diagonal filled with these sigma values !

	If the initial correlation (resp. covariance) matrix is not null, a specific pop-up window will appear to ask for the type of conversion. A bit as for the [[GPOrbit\|GPOrbit]] widget, it will be possible to do this conversion between correlation and covariance matrices (but not between the different type of parameters) using a kind of “pivot” notion.
