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))])
