Convert loop to vectorization

Here is simple code where I would like to remove for loop. A=[9;9;9]; c1=[2;3;5] for i=1:length(c1) c=c1(i,1); [B]=Subsum (A,c) i=i+1; end

Function subsum is defined as below

function [B] = Subsum (A,c) B=A-c; end

Desired output First loop B=[ 7 ;7;7] second loop B=[6;6;6] and Third loop B=[4;4;4]

A=[9;9;9]; 
c=[2;3;5];
b={(A-c)};
B=cell(1,length(c));
for i = 1:length(B)
B{i}=repmat(b{:}(i),numel(c),1);
end

what's your desired output?

Thanks for the answer in case I want output as first loop B=[ 7 ;7;7] second loop B=[6;6;6] and Third loop B=[4;4;4]

Then code is A=[9;9;9]; c1=[2; 3; 5]; for i=1:length(c1) c=c1(i,1) [B] = Subsum (A,c) i=i+1; end

How can I write this without loop

Your Answer was correct but I changed my question a bit
