Fill NaN matrix with vector of unequal sizes

Hi all,
I have the following code:
temp = {'AccNorm','GyrNorm'};
NSensors = 5;
for a = 1:length(temp)
for k = 1:NSensors
CMC_RT(k).RF.(temp{a}) = nan(10,2);
end
end
In which I just preallocate CMC_T with NaN values, because the 2 vectors I want to put in the matrix have different lengths.
However when I try to fill them up:
for a = 1:length(temp)
for k = 1:NSensors
CMC_RT(k).RF.GyrNorm = CMC_RTT.RF.(temp{a})(k,1:10)';
CMC_RT(k).RF.GyrNorm(:,2) = CMC_RTT.RF.(temp{a})(k,11:19)';
end
end
Matlab gives me the error: Unable to perform assignment because the size of the left side is 10-by-1 and the size of the right side is 9-by-1.
Which obviously makes sense, but I would think matlab would just fill the NaN matrix with the numbers and leave the NaN values for the ones where there is no substitute value. But this was apparently whishful thinking...
Any help on a idea for a solution would be much appreciated.
Thank you!

CMC_RT(k).RF.GyrNorm(1:10,1) = CMC_RTT.RF.(temp{a})(k,1:10);
CMC_RT(k).RF.GyrNorm(1:9,2) = CMC_RTT.RF.(temp{a})(k,11:19);
The complex conjugates are not required.

"I should do something like this?"
One loop should be sufficient:
n = cellfun(@numel,t);
m = nan(numel(t),max(n));
for k = 1:numel(t)
m(k,1:n(k)) = t{k};
end
This code assumes that cell array t and its content are vectors.
