The problem is that I have several variables in the for loop whose definition and value depend on the year suffix, that is they are constructed by combaining a letter (K,g, and so on) with the year number, so that they become K2006, g2006 and so on in the first iteration, K2007, g2007 and so on in the second iteration, and I have to consider also possible more years. If so, this manipulation of variables by using strings for the variable names is in general highly discouraged for a multitude of reasons (hard to read, hard to debug, etc). where filename is a cell array of a list of 4 file names and indx is the location of the files that the user selected from the list dialog box.
