— Function File: retsys = sysscale (sys, outscale, inscale, outname, inname)

scale inputs/outputs of a system.

Inputs

sys

Structured system.

outscale

inscale

Constant matrices of appropriate dimension.

outname

inname

Lists of strings with the names of respectively outputs and inputs.

Output

retsys

resulting open loop system:

               -----------    -------    -----------
               u --->| inscale |--->| sys |--->| outscale |---> y
               -----------    -------    -----------

If the input names and output names (each a list of strings) are not given and the scaling matrices are not square, then default names will be given to the inputs and/or outputs.

A warning message is printed if outscale attempts to add continuous system outputs to discrete system outputs; otherwise yd is set appropriately in the returned value of sys.
