When original data (instead of correlations, for example) is needed
as input for a multivariate operation, it has to be converted (from
a data list, table or file) to a matrix file by the
MAT SAVE DATA <Survo data> TO <MAT file> 
operation.
Observations and variables may be selected by the standard means of
Survo (i.e. by specifications IND, CASES, SELECT, VARS, MASK).
