I want to read the values from a file which is the following format into a matrix

@ STAGE_X_MIRROR
No   0    Pos_y     -234mm     Wx       10     Wxp        3
No   1    Pos_y     -232mm     Wx        8     Wxp        2
No   2    Pos_y     -230mm     Wx        8     Wxp        2
No   3    Pos_y     -228mm     Wx        8     Wxp        2
@ STAGE_Y_MIRROR
No   0    Pos_x     -164mm     Wy      -32     Wyp       -2
No   1    Pos_x     -162mm     Wy      -35     Wyp       -2
No   2    Pos_x     -160mm     Wy      -34     Wyp       -2
No   3    Pos_x     -158mm     Wy      -33     Wyp       -2

I need only the values Pos_y, Wx and Wxp and the next will be Pos_x, Wy and Wyp. That is the output of the matrices should be

matrix 1

-234 10 3
-232  8 2
-230  8 2

matrix 2

-164 -32 -2
-162 -35 -2

i coded to read from the file skip the first line then i said

data(iData,1:3) = sscanf(strLine,'%*s %*d %*s %g %*s %d %*s %d')'; - by this statement it was reading -234 in all the three.

please inform me if someone can do this even by anyother possible way also
