\(\text{DiagonalEntries}\)¶
You can use this function to obtain the diagnonal entries of a matrix.
You can use the \diagent
backslash command to insert this function.
The following variants of this function are available:
\(\text{ matrix } \text{DiagonalEntries} \left ( \text{<matrix>} \right )\)
The returned matrix will be the same type as \(\text{<matrix>}\). The returned value will be a column matrix with one entry per diagnonal entry in the the matrix.
Figure 126 shows the basic use of the \(\text{DiagonalEntries}\) function.
