sysdiag — block diagonal system connection

Calling sequence

r=sysdiag(a1,a2,...,an)

Description

Returns the block-diagonal system made with subsystems put in the main diagonal

ai: subsystems (i.e. gains, or linear systems in state-space or transfer form)

Used in particular for system interconnections.

Remark

At most 17 arguments.

Examples



 s=poly(0,'s')
 sysdiag(rand(2,2),1/(s+1),[1/(s-1);1/((s-2)*(s-3))])
 sysdiag(tf2ss(1/s),1/(s+1),[1/(s-1);1/((s-2)*(s-3))])

 s=poly(0,'s')
 sysdiag(rand(2,2),1/(s+1),[1/(s-1);1/((s-2)*(s-3))])
 sysdiag(tf2ss(1/s),1/(s+1),[1/(s-1);1/((s-2)*(s-3))])
