You don't need any more exact knowledge w/ textscan than you do w/ fscanf

The difficulty in the first that I was point you at is in the following...

The data line--
Step = 1 z = 0.0000 U_pitot= 8.030 U = 7.168

To read this, I used the following line of codes:
....
s=fscanf(fp,'U=%f');

Note there's no string 'U=' in the data line.

>> v=sscanf(l,'%*s = %f%*s = %f%*s = %f%*s%f')
v =
1.0000
0
8.0300
7.1680

I've a version that predates textscan() here so can't actually do an
example, but the above should be a hint.

Ya I just ignored the '=' sign and wrote s=fscanf(fp,'%*s%f\t') to read U = 7.168 and it worked. But why it ignores'=' for this particular case?
