there are lots of ways to do this, see num2str or using low level sprintf, a few examples:
fname = [ filename num2str(n) ];
fname = strcat ( filename, num2str(n) );
fname = sprintf ( '%s %i', filename, n );
I always use the last example

hi @Robert Cumming...i am using a nested for loop to place simulink blocks to form a 4 X 4 mesh of same element in combination with add_block and add_line function. how should i use num2str to name my elemens in the row differently than the elements in columns. e.g. for row elements, the blocks should bear the names B11 B12 B13 B14 and the next three rows should follow as...B21 B22 B23 B24 and so on until the 4x4th element to be B44
