Cannot use some Matlab MPC Toolbox functions

Question

I'm trying to use for example setoutdist Matlab function from the MPC Toolbox (I'm using Matlab R2013a on Windows 8.1). As a response I'm receiving:

    Undefined function 'setoutdist' for input arguments of type 'ss'.

I am able to get help about this function using help setoutdist. When I'm typing the function name and left parenthesis I'm receiving prompt with list of the arguments. When I'm using which setoutdist -all I'm receiving proper output:

C:\Program Files\MATLAB\R2013a\toolbox\mpc\mpc\@mpc\setoutdist.m  % mpc method code here

But the function doesn't work even in default Matlab path, so I don't think it is shadowed. The same is with the other functions, for example setindist, setestim, mpc_struct, etc. but mpc, mpcstate and mpcmove functions works correctly.

I was trying: clear all, clear classess, rehash toolbox, rehash pathreset, rehash toolboxreset, restoring default paths using pathtool. I've blocked the antivirus and added exeptions to it's list. I've even reinstalled my Matlab, nothing helped.

Maybe this is significant: when I'm trying to edit the setoutdist.m I'm receiving message that access is denied.

I will extremly appreciate any help...

How are you calling setoutdist? The correct syntax is one of the three (see documentation - for R2014b):

setoutdist(MPCobj,'integrators')
setoutdist(MPCobj,'remove',channels)
setoutdist(MPCobj,'model',model)

where MPCobj is a Model Predictive Controller object, created for example with the mpc function. It looks like from the error message that you are calling the function with a state-space object, which is not allowed (I'm guessing).
