Hi all
i have this code
for i=1:length(a)
C(i)=repmat(b(i),1,a(i))
end
where b is a cell array
16x5 double
16x5 double
13x5 double
and a is an array
[101,17,1]
i want to copy the first cell 101 times, the second cell, 17 times and last cell only one time, but using the upper code i can't do that...any idea?
Thank you for the help!!
Regards

"the cell and the matrix inside it"
That seems very unusual. So given this cell array:
C = {X,Y,Z}
you want to repmat both the cells and the matrices to get this:
{[X,X,X...X],[X,X,X,...X],...,[X,X,X,...X],[Y,Y,Y,...Y],[Y,Y,Y,...Y],...,[Y,Y,Y,...Y],[Z,Z,Z,...,Z],...,[Z,Z,Z,...Z]}
I would have expected either of these:
{X,X,...,X,Y,Y,...Y,Z,Z,...Z} % repmat the cells themselves
{[X,X,..,X],[Y,Y,...,Y],[Z,Z,...,Z]} % repmat the arrays inside the cells

for i=1:length(a)
C{i}=repmat(b{i},1,a(i));
end

count=1;
for i=1:length(a)
for k=1:a(i)
C{count}=b{i};
count=count+1;
end
end

To replicate the cells you can use repmat or repelem depending on whether you want ABCABCABCABC... or AAAABBBBCCCC ... In other words, how do you want the replicates to be collated? Suitable for stapling into packets or suitable for making stacks of loose handouts for students to select from piles?
X = {1:3, 4:7, [8 9]}; % A is 1:3, B is 4:7, C is [8 9]
Y1 = repmat(X, [1 2]) % ABCABC
Y2 = repelem(X, [2 3 4]) % AABBBCCCC
Or do you want to replicate the contents of the cells?
X2 = {repmat(1:3, [2 1]), repmat(4:7, [3 3]), repmat([8 9], 1, 4)}
% X2 contains a 2-by-3, a 3-by-12, and a 1-by-8
