Matrices   

A matrix is a 2-dimensional array of values. Matrices are calculated by the Principal Components operation and by the Factor Analysis operation. The Principal Components operation calculates a.o. a variance-covariance matrix and the Factor Analysis operation calculates a.o. a correlation matrix. The matrices can be shown.

When a matrix has been calculated, the Matrix Properties sheet lists some additional information on the matrix, namely the total variances in the output bands.
