split a 2d matrix and create new 3d matrix from the results of the 2d matrix

hej !

i have a matrix T_A (size 12x11). i would like to split this matrix the way, i will get 3d matrix of the size (24x11x12). the way i want to do it is to take each raw from the T_A matrix and multiply it by a size i want to get that is: T_A(i,:).* ones(24,11) so as a result i will get a matrix with 11 "vertically-same" values (i pasted my code below, but i am doing sth wrond and i am getting an error). then i should get 12 individual matrixes and connect them as a one 3d matrix, but i am strugling how to do it. any help would be grateful... thank you in advance !

T_A = [1.9563    1.8572    1.7581    1.6590    1.5600    1.4609    1.3618    1.2627    1.1636    1.0645    0.9654

for i = 1:11
    Matrix_T_A(24,i) = T_A(i,:).* ones(24,11)
end

I believe this should do what you want:

Matrix_T_A = permute(repmat(T_A, 1, 1, 24), [3 2 1]);

Using the for loop, T_A(i,:).* ones(24,11) is a 24x11 matrix, so it needs a 24x11 space within Matrix_T_A for storage:

Matrix_T_A2 = ones(24,11,12);
for i = 1:12
    Matrix_T_A2(:,:,i) = T_A(i,:).* ones(24,11);
end


>> isequal(Matrix_T_A, Matrix_T_A2)

works perfectly !!! thx a lot !!!!

Answer 2

[TADA]

If I got it right

Matrix_T_A = repmat(reshape(T_A', 1, size(x, 2), size(x,1)), 24, 1, 1)

i am getting an error, but the answer above is correct, thank you !!
