Question

For example, if I have the file A.dat and B.datand

A.dat have

1 2 3

4 5 6

7 8 9

and the file B.dat is empty at first.

How can I (using Matlab functions) open the file B.dat print the A.dat content to it and print another entries like

10 11 12

13 14 15

?

I tried

fileA=fopen('A.dat','r')

fileB=fopen('B.dat','w');

fprintf(fileB,fileA);

or

fprintf(fileB,fscanf(fileA));

or

fprintf(fileB,fscanf(fileA,'%s'));

but none works.

Answer 1

You seem to be confused as to what the functions are used for. fprintfand fscanf are probably not what you are looking for (but can be useful).

Try using fread and fwrite instead:

dataA = fread(fileA)
fwrite(fileB, dataA)
