creation of matrices based on output

Hi, I have the program below which when run gives extracted matrices with corresponding means. My problem is to tell the program to ouput all the means inside onesinlge matrix. Can someone assist me with this kindly. My input for A and B were A=[1 1 1 1 2 2 2 2 3 3 3 3]'; B=[3 4 6 7 8 9 0 12 4 5 6 8]';

%when this code is run and you input A and B which were (A=[1 1 1 1 2 2 2 2 3 3 3 3]'; B=[3 4 6 7 8 9 0 12 4 5 6 8]';)

A=input('input sample matrix\n');

B=input('enter the second matrix\n');

C=[A B];

for i=1:1:3

selectedRowsLogicalIndices = A == i;

subsetBdata = B(selectedRowsLogicalIndices)

mean(subsetBdata)

end

Below are the reulst that i got;

subsetBdata =

3

4

6

7

ans =

5

subsetBdata =

8

9

0

12

ans =

7.2500

subsetBdata =

4

5

6

8

ans =

5.7500

>>

I want all the means to be in matrix form like below;

ouput I want is below;

[5 7.25 5.75]'

or a matrix of all the subdatasets

Why can't you store the results in a vector using your loop variable as the index?

@Rik if you dont mind, i request you just demostrate with an example. Am in the process of learning matlab, therefore I may not much experienced. Kindly.

output(i) = value

@Rik thank you, this tip just gave me a clue and it worked just right. Thank you so much.

[Sargondjani]

D(i,1) = mean(subsetBdata)

What if I wanted to do the same with the vectors, kindly give some clue @Sargondjani

[Walter Roberson]

output(i, :) = rowvector
output(:, i) = columnvector
