I have 2 matrices, A(10,10) and B(10,20). which have same size in row and different in column because matrix A consist of 10 variables, which each variables have different size in column. and the column size depend on user input (in matrix), if the input are [1 1 2 1 2 1 1 2 1 1] then matrix A have 13 column. matrix B also consist of 10 variables, column size in matrix B depend on user input either, if the input is 2 then each variables have the same size of column (2), and the total matrix B have 2*10=20 column.

Now,i wanna create matrix C which consist of A and B with the structure like this C=[A(:,1) B(:,1:2) A(:,2) B(:,3:4) A(:,3:4) B(:,5:6) A(:,5) B(:,7:8) A(:,6:7) B(:,9:10) A(:,8) B(:,11:12) A(:,9) B(:,13:14) A(:,10:11) B(:,15:16) A(:,12) B(:,17:18) A(:,13) B(:,19:20)].

this question is rather similar to my question before, but both matrice have the same size before.please help.

thanks in advance.

在 MATLAB Online 中打开

A = randi([100 200],10,10);
B = randi(99,10,20);
a = [1 1 2 1 2 1 1 2 1 1];
b = 2; 
k1 = arrayfun(@(i1)A(:,i1*ones(a(i1),1)),1:size(A,2),'un',0);
k2 = mat2cell(B,size(B,1),ones(size(B,2)/b,1)*b);
out = cell(1,numel(k1)*2);
out(1:2:end) = k1;
out(2:2:end) = k2;
out = cell2mat(out);
