program not working in newer version of matlab

Good afternoon Matlab Community, At one point I was very proficient in Matlab commands and recently, gladly, realized that I will be using it a lot now in pharmacology for modeling and simulations.

Currently, in the lab, we have a program that runs only on Matlab 2009 (not sure if a or b) or earlier.

I installed Matlab 2014a and am getting this error message:

    >> TapOpen
    Undefined function 'TapSetUp' for input arguments of type 'char'.

    Error in TapOpen (line 101)
        TapSetUp([nstr,estr]);

It appears that the "[nstr,estr]" function is not working in the newer version of Matlab. I then installed the 2011b version and I am getting the same error message.

Is there any way, I can update these functions into the newer version of Matlab or what function calls am I supposed to change?

Thank you for your help.

Sincerely, Andy

What does

    which TapSetUp

return?

I assume TapSetUp is not a subfunction of TapOpen

[per isakson]

Besides that I dislike spaces in filespecs, I cannot see anything wrong. Try (in the command window)

    >> TapSetUp('abcd.efg')

it ought to throw an error, Cannot find file ...

[per isakson]

"It appears that the "[nstr,estr]" function is not working in the newer version" &nbsp I does, try

    >> ['abcd','.efg']

it ought to return on string 'abcd.efg'

That is not a command that ships with MATLAB but rather one that you got from someone else or downloaded or wrote. On the machine with it:

which -all TapSetUp

This will tell you where it is. Copy it onto the new machine, and add that directory to the path using addpath.
