Assign 3-by-1 matrix to image 3D matrix

Hello,

I get color values from loop and impixel function.

Color values is 1x3 matrix.

For my calculate must be color dimension like 3x1, therefoe transponing. Result is 3x1 matrix (LMS).

My question is:

how assign 3x1 (LMS) matrix to new matrix (A_LMS) which will be built (and dimension increase) simultaneously. New matrix (A_LMS) is the same size of original image (A)?

for Z = 1 : Za 
    for Y = 1 : Ya
        for X = 1 : Xa
            color = impixel(A, X, Y); 
            LMS = mapM*(color.');
            A_LMS(, , Z) = LMS.';
        end       
    end   
end

I solve this issue:

for Z = 1 : Za 
    for Y = 1 : Ya
        for X = 1 : Xa
            color = impixel(A, X, Y); 
            LMS = mapM*(color.');
            [Xlms, Ylms] = size(LMS);
            for Y_LMS = 1 : Ylms
                for X_LMS = 1 : Xlms 
                    A_LMS(X, Y, Z) = LMS(X_LMS, Y_LMS);
                end
            end
        end       
    end   
end
