I think i found a way a little more easy. Because there is already a function in excel for hyperlink, I did
first: a list with all the names of the file and there path through matlab to be paste in excell
second: then by using strcat i was able to put in a loop the cells of the list and do a =hyperlink(cell1, cell2) string in matlab to be paste where i want the hyperlinks to be in excel and it worked
h = ['=Hyperlink(']
h1 = cell1number e.g A13
h2 = ','
h3 = cell2number e.g B13
h4 = ')'
makes '=Hyperlink(A13, B13)'
