MATLAB: Cell operation

cell cat

There is a cell array. A = {'ab', 'bc', 'cd'};

I'd like to get a new cell array, like: B = {'ab', 'ab', 'ab', 'bc', 'bc', 'bc', 'cd', 'cd', 'cd'}.

How to get this without using loop?

Thanks

Best Answer

B = repmat(A, 3, 1);  %do the duplication
B = B(:).' ; turn the result in to a row vector

a = 7;
b = 4;
c = rem(a / b, 1)

c = a / b;
d = c - floor(c);

Not sure if the way you described is the best way to proceed but here you can make use of cellfun to achieve I think what you described.

A = rand(12,100);
Ac = mat2cell(A,[6,6],ones(1,100));
B = rand(101,6);
Bc = mat2cell(B(2:end,:),ones(100,1),6);

Created sample data. Ac is a 2x100 cell array with 6x1 vector in each cell. Bc is a 100x1 cell array with 1x6 vector in each cell. Now cellfun to multiply vectors in each cells

BcAc1 = cellfun(@mtimes,Bc',Ac(1,:), 'UniformOutput', false);
BcAc2 = cellfun(@mtimes,Bc',Ac(2,:), 'UniformOutput', false);
% Concatinate the results to create 2x100 cell array with a scalar in each cell
BcAc = [BcAc1; BcAc2];
whos BcAc
