Skipping lines of code based on available functions (s) / toolbars

Question

Context

At work, I built a graphical interface for registering images on several microscopy images. The Parallel Processing Toolbox is installed on the computer that I use (i.e. at work), so I can use spmd blocks to distribute work on computer cores.

First I create a codistributed array to split my array into smaller pieces:

spmd

    DistributedCell = codistributed.cell(NumberFrames)
   ...
end

Everything is fine until I run the code on my own laptop on which the Parallel Processing Toolbox is not installed. Obviously, I cannot use blocks spmdand arrays with distributed distribution, so I wrote non-parallel code for registering images, which works equally well, but takes longer.

Problem

The problem I am facing is that the code in the blocks spmdneeds to be commented out when I use my home laptop, otherwise Matlab complains that:

MATLAB cannot determine whether "codistributed"
refers to a function or variable.

So, even if I check whether the PP toolbox is installed (or not), and use the condition to execute different commands, depending on whether it is or not, as follows:

%// Check for parallel toolbox installed
if ~isempty(ver('parallel'))

  NON-PARALLEL code...

else

  PARALLEL code...
