WebMay 4, 2024 · 0. In loose terms, the determinant can be considered the "size" of a matrix (unrelated to it's nxm size) If the matrix is considered an operator or linear transformation, the determinant is then the "scale factor" which describes how the operand transforms in size (vector norm, for example) Sep 1, 2006. #3. matt grime. WebThe normalized gene expression matrix and platform annotation profiles were downloaded. Based on the annotation information, the probes were matched to the gene symbols. For multiple probes corresponding to one gene symbol, we calculated the gene expression values by averaging across all the matched probe sets of a gene.
