matlab - mat2cell to divide 3D image into blocks -

-

i have 4d image of size 60 x 80 x 12 x 350, i.e. 3d image each voxel has time series (of 350).

now want use mat2cell divide 3d image cubes of dimension k*k*k. each voxel in cube vector of size 350 (the time series).

i think mat2cell don't know how exactly. each cell should contain in end 3d block of image each voxel of block vector of size 350.

assuming 4d matrix called m. need have vectors elements sum size(m, i) i = 1:4. assuming k has value, tried both 4 (because it's common factor of sizes specified) , 3 (because it's not).

k = 3; mprime = mat2cell(m, ...     [k*ones(1, floor(size(m,1)/k)), mod(size(m,1), k)], ...     [k*ones(1, floor(size(m,2)/k)), mod(size(m,2), k)], ...     [k*ones(1, floor(size(m,3)/k)), mod(size(m,3), k)], ...     ones(1, size(m,4)));

i have following code almost works properly; private void cbstatus_drawitem(object sender, listboxdrawitemeventargs e) { string item = e.item string; if (item != null) { switch (item) { case "1": e.appearance.forecolor = color.green; e.appearance.backcolor = color.green; break; case "2": e.appearance.forecolor = color.orange; e.appearance.backcolor = color.orange; break; case "3": e.appearance.forecolor = color.red; e.appearance.backcolor = color.red; break; } } } when dropdown shown, items forecolor correct, backcolor remains whatever backcolor of theme is; i.e. if i've got set dark theme, backcolor dark, cells in gridview, rather being green/orange/red. i've tried setting e.appearance.options.usebackcolor trying set e....
