How to debug?
1) Since it is not properly identified with whereis() in the error 
message => look for the plotting instruction yielding the error. To do 
so, no chance to succeed by running the whole script in a blind way. Run 
it step by step, selecting the whole starting part, down to the first 
plotting instruction that could trigger the error, and run the 
selection. If there is no error, select the following lines down to the 
next plotting instruction ; run them, and see. etc.. down to the plot 
yielding the error.
2) For this plotting instruction : display the size of each of the first 
two input parameters, and compare them.
3) Look in the help page of the involved plot/plot2 instruction whether 
the format of input parameters that you try to pas to the plot is 
accepted or not.

You will see that it is not the case. There are indeed mismatching 
parameters.
4) correct your program.
5) test it.
