I am running this code but after running I get the error Undefined variable cell_worker_sum. and I cannot check the values of variables in the last loop.. Is there any error in applying IF condition? _I want to apply the loop on those matrices of all_comb_of_workers in which sum of each column is 1 or greater than one.

I suggest you use the debugging capability. Specifically, set a breakpoint at line 100, and see if the values of columnSums are what you expect.
Making a guess, though ...
Did you mean to use
if any(columnSums>1)
rather than
if all(columnSums>1)
?

is this logical statement correct according to the condition? I dont think its working as I want it to..

I don't know, and your language is not clear enough for me to be sure. Maybe you could give several examples of values of columnsSums, and whether they should trigger the if statement or not.
Again, I suggest you use the debugger, and check for yourself.
