Hi,
In the attached data, from the columns 225 to 247, I need to check does any values in the row 1 exceeds 600. If exceeds, it should store value 1, otherwise 0 in the another array named say X.
Could someone help me with this?

If undestood correctly your question, logical indexing would be one of the easy solutions:
X2 = load('matlab.mat').x2;
Y = X2;
D = X2(1, 225:247);
%% Condition 1
D(D>600)=1;
X2(1, 225:247)=D; % Original X2 values are changed
X_X2 = X2(1, 225:247) %# Check the substituted values
%% Condition 2
D = Y(1, 225:247);
D((D<600)) = 0;
D((D>600)) = 1;
X = Y;
X(1, 225:247)=D;
X_X = X(1, 225:247) %# Check the substituted values
%% Put both condition findings into X2 imported original data
X2(1, 225:247)=X_X;
