rsf2csf

Convert real Schur form to complex Schur form.

Syntax

• [Uc, Tc] = rsf2csf(U, T)

Input argument

• U - unitary matrix (double or single, real or complex)
• T - schur form (double or single, real or complex)

Output argument

• Uc - transformed unitary matrix
• Tc - transformed schur form

Description

[Uc, Tc] = rsf2csf(U, T) transforms the outputs of [U, T] = schur(X) for real matrices X from real Schur form to complex Schur form.

Example

X = [1,     1,     1,     3;
     1,     2,     1,     1;
     1,     1,     3,     1;
    -2,     1,     1,     4];
[U, T] = schur(X)
[Uc, Tc] = rsf2csf(U, T)
