MATLAB: Making a matrix dimension biggere

MATLABmatrix manipulation

Okay I have two matrices

k_fil =

   -46   -43   -26   -14     7    19    11    32    39    45    45
     0     4     7     7    44    44     7     7    15    15     0

and

k_omv =

    45    45    39    32    11    19     7   -14   -26   -43   -46
     0   -15   -15    -7    -7   -44   -44    -7    -7    -4     0

How do i add these, so that i get a matrix that is 2×22 ??

Try

 k = [k_fil k_omv]

alternatively, you could use

 k = horzcat(k_fil, k_omv)

assuming that you do want to concatenate the arrays.

You could also use

 out= fliplr(k_minus)

This flips the matrix left-right http://www.mathworks.com/help/matlab/ref/fliplr.html

MATLAB: How to calculate the proportion of the color in Lab coordinate

Try this example

im = imread('peacock.jpg');
im_lab = rgb2lab(im);
L = round(im_lab(:,:,1));
a = round(im_lab(:,:,2));
b = round(im_lab(:,:,3));
L_partition = {[0, 30], [31, 61], [62, 100]};
a_partition = {[-128, -44], [-43, 41], [42, 127]};
b_partition = {[-128, -44], [-43, 41], [42, 127]};
combs = combvec(1:3,1:3,1:3).';
in_range = @(frame, range) (frame >= range(1)) & (frame <= range(2));
result = cell(size(combs,1), 4);
for i=1:size(combs,1)
    comb = combs(i,:);
    l_part = L_partition{comb(1)};
    a_part = a_partition{comb(2)};
    b_part = b_partition{comb(3)};
    
    pxlSum = sum(in_range(L,l_part).*in_range(a,a_part).*in_range(b,b_part), 'all');
    
    result(i,:) = [{l_part} {a_part} {b_part} {pxlSum}];
end
T = cell2table(result, 'VariableNames', {'L range', 'a range', 'b range', 'pixel count'});
disp(T)

Result:

     L range       a range         b range       pixel count
