Hello,
I got this error, here is my code, can you help me out.
for info: Uns_states is the matrix whose 1st row I'm using so I will only show first row for the sake of simplicity Uns_states=[1 0 0 0 0 1 1 1 1 1 1 1 1 1 1 1 1 0 0 0 0 0 0 0 ]
app= containers.Map({ 'Name', 'Power', 'cyclic', 'E_curr', 'E_max', 'E_min','loss_idle','loss_use','type_of_app','states', 'time'},...
{'app', 0.075, false, 0, 0.075,0,0,0, 'none',Uns_states(1,:),14});
Now I want to call the element of Uns_states one by one. That is how I'm doing that app('states')(1,3). Can someone guide me how to do that.
Thanks in advance.

You need to use a temporary variable, or you need to use a helper function, or you need to use the subsref function (which has an exceptionally ugly calling sequence)
