I want to construct three tests.

If I have four columns, x1, x2, x3 and x4 I want to create the following three tests for the first values of all the four columns

x1=first_value_of column
x1>first_value_of_column
x1<first_value_of_column

Is there an easy way to do this? Please explain in simple terms. I am new to matlab

Hi Kunal,

As I understand, you are trying to compare a scalar value with a column vector. Consider the following example where "t" is a row vector from 1 to 10:

>> t = 1:10; % create row-vector from 1 to 10
>> t = t'; % transpose t so it is now a column vector.
>> t(1) < t; 
>> t(1) == t;

In this code I am comparing the first element of "t" with the entire column vector.
