Can't use Matlab Toolbox functions

Dear All,

I am using Matlab 2013b, and the "ver" command produces info as shown at the end of this message.

Although I can find many signal processing functions, e.g. butter.m, under directory "Matlab2013b\Toolbox\signal\signal", I can't use them. For instance, typing in "[z,p,k] = butter(6,0.7,'high')" in the matalb command window generates an error "Undefined function 'butter' for input arguments of type 'double'". Then I manually added the Toolbox folder and sub-folders into path, it did not resolve the problem. Then I typed in "which butter", it shows "C:\Program Files\Matlab\2013b\tool box\signal\eml\butter.m % Has no license available".

I wonder does this mean I do not have a valid license to use the signal processing tool box even though the tool box is installed as indicated by the "ver" command as shown below?

Thanks for your advice and help in advance.

Installing the software does not mean that you are licensed to use it. You need to activate the license for the toolbox, or you need to update your license file. If you are the listed asset manager or the technical contact then you can use the License Center to fetch the license file. (Provided you purchased the license, that is.)
