Undefined function or variable 'cellmat'.

I am new to matlab and trying to run some existing code that other developers can run without any issues but on my machine it gives below error. I have not found any suitable explanation to resolve this in documentation of other forum. I am using R2017a.

Undefined function or variable 'cellmat'.

Error in **** (line 74)
            **    = cellmat(abc,k);

Error in *** (line 32)
   ***

Error in *** (line 136)

Please advise.

Thanks

cellmat appears to be part of the Neural Network toolbox.

If abc and k are scalar values, then cellmat(abc,k) would be the same as

repmat({0}, abc, k)

Thanks, so does it mean this tool box is not enabled for me, how do i do that? Thanks!

It sounds as if the toolbox is not licensed for you, or not installed for you.

If your code uses cellmat() then it might use other functions from the Neural Network toolbox, in which case you would need to obtain the toolbox.

However, sometimes people happen to use a utility routine from a toolbox in code not related to the toolbox. If your code has nothing to do with Neural Network work, then instead of installing the toolbox, you code replace this particular utility routine invocation with a file cellmat.m

function r = cellmat(A, B)
  r = repmat({0}, A, B);
