hello everyone,
i am trying to read from a text file which has the following format
X: 549.123 Y: -100.235 Z: -230.89
X: 550.123 Y: -101.235 Z: -231.89
X: 551.123 Y: -102.235 Z: -232.89
X: 552.123 Y: -103.235 Z: -233.89
X: 553.123 Y: -104.235 Z: -234.89
the problem is when i read using textscan it stores the data in 3*10 cells where the first cell format is in the first column X: and in second column 549.123.
i want to store data in 3 matrices each of 1*5 ?
eagerly waiting for a reply.

Consider you have your data in file doc.txt, your ouput matrices are x_val,y_val, and z_val
fileID = fopen('doc.txt');
C = textscan(fileID, '%s %f32 %s %f32 %s %f32');
fclose(fileID);
x_val=cell2mat(C(:,2))
y_val=cell2mat(C(:,4))
z_val=cell2mat(C(:,6))
Output is
x_val =
549.12
550.12
551.12
552.12
553.12
y_val =
-100.24
-101.24
-102.24
-103.24
-104.24
z_val =
-230.89
-231.89
-232.89
-233.89
-234.89
doc.txt is as follows
X: 549.123 Y: -100.235 Z: -230.89
X: 550.123 Y: -101.235 Z: -231.89
X: 551.123 Y: -102.235 Z: -232.89
X: 552.123 Y: -103.235 Z: -233.89
X: 553.123 Y: -104.235 Z: -234.89
