MATLAB: For loop indexing and skip numbers

for loopskip

Hi,

I need to include for loop in MATLAB to start with 2:13. But I need to start with 2,3,4 and skip 5 and again 6,7,8 and skip 9 and 10,11,12 until 13.

How can I implement this is for loop?

Many thanks in advance.

You can also use

 ix = floor((4*(1:n)+2)/3);

where n is the desired length of the output.

start=[1 3 4];
rowSize=2;
out = cell2mat(arrayfun(@(i1)A(i1,start(i1)+(0:rowSize)),(1:size(A,1))','un',0));

start=[1 3 4];
rowSize=2;
n = size(A,1);
out = A(bsxfun(@plus,(bsxfun(@plus,start',0:rowSize)-1)*n,(1:n)'));

E.g., is this the type of indexing you want?

for j = 1:4:100  % Index through 1x100 cell
    temp = values(j:j+3); % Pick off the 4 cells
    for k = 1:4 
        % Use temp{k} here
    end
end
