\(\text{Diagonal}\)

You can use the \(\text{Diagonal}\) function to return a diagonal matrix from supplied values in another matrix.

You can use the \diagonal backslash command to insert this function.

The following variants of this function are available:

• \(\text{matrix } \text{Diagonal} \left ( \text{<matrix>} \right )\)

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 125 shows the basic use of the \(\text{DiagonalEntries}\) function.
