Possible bug in TOPAS engine with dij calculation

[remocristoforetti]

strjoint requires a string not a char array. This is a possible fix, I only tested in one specific case, but it's a small fix.

Can you explain the issue?

A problem of this proposed fix is that "string" does not exist in Octave. We need to work with char arrays.

Ah I see, the error is triggered by strjoin at line 2078. Possibly the char array imageName is not accepted as a valid input.
Avoiding the use of strjoin seams to work as well

But strjoin({'test','test2'},';') works without issues on cell arrays of chars, so I still don't get it.

Ah I guess that imageName already is a joined char array, so we don't need strjoin.
