Hello everyone,
I am working on a project for MCDM. I am using AHP method. I need help to apply an algorithm.
I have 4 matrices of 199X4 doubles. i.e.
row1 = [C11 C12 C13 C14];
row2 = [C21 C22 C23 C24];
row3 = [C31 C32 C33 C34];
row4 = [C41 C42 C43 C44];
where C11.....C44 are 199X1 doubles each.
Now, I have to make pairwise comparision matrix from rows of each given matrices. like
CompMat = [row1(1,:); row2(1,:); row3(1,:); row4(1,:)];
Next, I have to apply a function(Which I have already made) to calculate Consistancy. i.e.
CR = ConsistencyAHP( CompMat );
Now, task is to write a script using loops which can give me CR vector for every matrices formed from first row to 199th row.
Thanks in advance.

Using a for-loop will be easiest
row1 = [C11 C12 C13 C14];
row2 = [C21 C22 C23 C24];
row3 = [C31 C32 C33 C34];
row4 = [C41 C42 C43 C44];
CR = zeros(size(row1,1),1); % does ConsistencyAHP return a scalar??
for i=1:size(row1,1)
CompMat = [row1(i,:); row2(i,:); row3(i,:); row4(i,:)];
CR(i) = ConsistencyAHP(CompMat);
end

row3 = [C31 C32 C33 C34];
row4 = [C41 C42 C43 C44];
CR = zeros (size (row1,1), 1); % Yes, ConsistencyAHP return a scalar ??
for i = 1: size (row1,1)
CompMat = [row1(i, :); row2(i, :); row3(i, :); row4(i, :)];
CR (i) = ConsistencyAHP (CompMat);
end
