I have

B=[1,1;2,2;3,40;4,10;5,15;6,19;7,22];
c={[1,10,15],[15,19,22],[1,2,40]};

Matrix B shows that 4 is correspond to10 or 7 correspond to 22 or 3 correspond to 40 .

So I want to change c according to second column of B

result should be

c_new={[1,4,5],[5,6,7],[1,2,3]};

Solution 1:

c_new = cell(size(c));
for kk = 1:numel(c)
  c_new{kk} = interp1(B(:,2),B(:,1),c{kk});
end

Solution 2:

% "Solution 1" in 1 line
c_new = cellfun(@(x) interp1(B(:,2),B(:,1),x),c,'UniformOutput',false);
