image processing - How to assign a value to multiple cells in a n-dimensional array in Octave -

-

suppose have 3x3x3 3d-array called , 3x3 matrix called b, created following:

a = zeros(3,3,3); b = magic(3);

my intention turn elements @ 2nd , 3rd positions of a's 3rd dimension matrix b, like

a(:,:,1) =           a(:,:,2) =           a(:,:,3) =     0   0   0          8   1   6          8   1   6    0   0   0          3   5   7          3   5   7    0   0   0          4   9   2          4   9   2

my first try make

a(:,:,2:3) = b

but following:

error: a(i,j,...) = x: dimensions mismatch

it feels strange me, since, instance,

b(1,1:2) = 10

would produce correct result.

how solve this?

thanks in advance

forget it, solved following:

a(:,:,1:2) = repmat(b, [1 1 2])

:)
