Mu Analysis and Synthesis Toolbox

unum returns the SYSTEM matrix input dimension

xnum returns the SYSTEM matrix state dimension

ynum returns the SYSTEM matrix output dimension

Syntax

• numinputs = unum(sys) 
  numstates = xnum(sys) 
  numoutputs = ynum(mat)
  

Description
unum returns the input (column) dimension of SYSTEM, CONSTANT, and VARYING matrices.

xnum returns the state dimension of SYSTEM matrices.

ynum returns the output (row) dimension of SYSTEM, CONSTANT, and VARYING matrices.

Examples

• sys = sysrand(3,4,5); 
  xnum(sys) 
  ans = 
      3 
  unum(sys) 
  ans = 
      5 
  ynum(sys) 
  ans = 
      4 
  mat = crand(17,9); 
  xnum(mat) 
  ans = 
      0 
  unum(mat) 
  ans = 
      9 
  ynum(mat) 
  ans = 
      17
