Description
The vslSSEditCovCor routine replaces pointers to the array of means, covariance/correlation arrays, and their storage format with values passed as corresponding parameters of the routine. If you pass a value of NULL for a specific input parameter, the value of that parameter in the task descriptor is unchanged.
The storage parameters, cov_storage and cor_storage, describe the storage format used for the p-by-p symmetric variance-covariance/correlation/cross-product matrix C. The matrix C can be described as
Table "Storage formats of a variance-covariance/correlation/cross-product matrix" shows how the matrix is stored in a one-dimensional array cp for different values of the storage parameters.
Parameter |
Description |
---|---|
VSL_SS_MATRIX_STORAGE_FULL |
The array cp contains all elements of the matrix stored sequentially, column-by-column:
The size of array cp is p*p. |
VSL_SS_MATRIX_STORAGE_L_PACKED |
The array cp contains the lower triangular part of the symmetric matrix stored sequentially, column-by-column:
The size of the array is p*(p+ 1)/2. |
VSL_SS_MATRIX_STORAGE_U_PACKED |
The array cp contains the upper triangular part of the symmetric matrix stored sequentially, column-by-column:
The size of the array is p*(p+ 1)/2. |
