The Schur function has A and flag for a real matrix A, in flag there are two types of flag values one is complex and another is real, which type gives the heading

Hello

I am using schur function in my there I want to know which form is upper triangular with the eigenvalues of A on the diagonal? I am working on the schur function and wanted to know on this.

Hi Karthik,

As per my understanding, you are interested to find which form of ‘schur’ function flag form is triangular with the eigenvalues of A on the diagonal.

If A is complex, ‘schur’ returns the complex Schur form in matrix T and flag is ignored. The complex Schur form is upper triangular with the eigenvalues of A on the diagonal.

For further reference, please could you check this link to know more about ‘schur’ function:

I hope this resolves your issue.
