Is there any way how to effectively generalize movmedian function to work with variable window length or local variable k-point median values, where k is vector with the same length as length of input vector (lenght(x) = lenght(k))?
Example:
x = 1:6
k = 2,3,3,5,3,2
M = movmedian_vk(x,k)
M = 1, 2, 3, 4, 5, 5.5
My naive solution looks like:
function M = movmedian_vk(x,k)

if length(k) ~= length(x)
error(‘Incomaptible input data’)
end

M = zeros(size(x));
[uk,~,ck] = unique(k);
for i = 1:length(uk)
M_i = movmedian(x,uk(i));
I_i = (ck == i);
M(I_i) = M_i(I_i);
end
