I basically have a number of matrixes (N,1) that i want to split up into smaller arrays. I want to split them into say 10 pieces irrelevant of the number of components. I tried using reshape but that has issues with prime numbers

How can i split an N length array into 10 other pieces and store as a cell?

 N = 613;
 P = 10;
 X = rand(N, 1); 
 r = diff(fix(linspace(0, N, P+1)))
 C = mat2cell(X, r, 1)

Use matcell, look at this example

N=randi(100,100,1)
B=mat2cell(N,10*ones(10,1),1)

在 MATLAB Online 中打开

N=randi(100,613,1)
n=numel(N)
m=fix(n/100)
p=mod(n,100)
B=[mat2cell(N(1:m*100),100*ones(m,1),1);{N(100*m+1:100*m+p)}]

Ok thanks Ill have a look.. I found a way to do it also by just inserting a row of zeros and replacing the appropriate rows..Yours looks more simple though =]
