I think this will help you:

close all;
clear all;
workspace; % Display workspace panel.

% Create a 1000 row by 10 column array of
% random integers in the range 0-49.
T = uint8(50*rand(1000, 10));

% Set a column where we'll look for a certain T value.
b = 8;

% Find where T = 42 in this column (column b=8)
aAtTEquals42 = find(T(:,b)==42)
