RESHAPE command in MATLAB

I am working on this piece of code which is basically k-means clustering and I'm really stuck at a point where cell needs to be reshaped into matrix:
vec_dist(i)=dist(s(i),reshape(cell2mat(codebook),L,length(codebook)));
with error: Error using reshape To RESHAPE the number of elements must not change.
Any help would be highly appreciated.

Do you understand why the following example produces an error? The error your code gives is due to the same thing.
>> reshape(rand(2,3),5,1)
Error using reshape
To RESHAPE the number of elements must not change.

Did you understand the example I posted? The error you're getting pertains to the sizes and values of the arguments, not their data type.
By entering the values of L and length(codebook), RESHAPE expects that the array you're trying to reshape has L*length(codebook) elements in it. That is apparently not the number of elements in the array cell2mat(codebook). If this surprises you, use DBSTOP as I suggested to see how many elements there actually are.
