Question

I am working with some matlab code I inhereted from another person, I dont understand the meaning of the line q =[q; qi’]. I feel like i should be able to just remove it, so that q = distribuc…

function [ q ] = ObtainHistogramForEachTarget( state, numberOfTargets, image, q )

    for i=1 : numberOfTargets
        qi = distribucion_color_bin_RGB2(state(i).xPosition,state(i).yPosition,state(i).size,image,2);
        q = [q; qi'];
    end
end

Can anyone explain this to me?

Answer 1

MATLAB has several built-in functions to manipulate matrices. The special character, ', for prime denotes the transpose of a matrix.

The statement A = [ 1 2 3;4 5 6;7 8 9]' produces the matrix

A = 
   1 4 7 
   2 5 8
   3 6 9

hope this helps
