select

Hello,

In attachment my dataset. I have to select the 3 first columns and the 8 first rows, all the data in it. How do I do this?

A(1:8,1:3)

Example

A=randi(9,10,5)
out=A(1:8,1:3)

 mpw.hid=='103'

With

 strcmp(mpw.hid,'103')

myArray = [1 2 3; 4 5 6; 7 8 9; 10 11 12; 13 14 15];
result = myArray( [1 3 4], : );
