Test script
---------------------------------------------------
$ cat test.m
fh = popen("cat test.dat","r")
[i1,i2,i3] = fscanf(fh,"%i %i %i\n","C")
tval = i1*i2
[s1,s2,s3] = fscanf(fh,"%s %s %s\n","C")
i1 = str2num(s1);
i2 = str2num(s2);
tval = i1*i2
pclose(fh)

Output
---------------------------------------------------
