how to separate the non-zero elements from an array

suppose i have a column matrix with non zero elements in between the zeros. i want to put the nonzero values in a cell of different groups of nonzero integers.

for example x=[ 0 0 0 1 2 3 0 0 2 3 5 6 0 0 2 5 0]

[1 2 3] is one group [2 3 5 6 ] is the next. i want all these groups in one cell.

A = [ 0 0 0 1 2 3 0 0 2 3 5 6 0 0 2 5 0] ;
ii = zeros(size(A));
jj = A > 0;
ii(strfind([0,jj(:)'],[0 1])) = 1;
idx = cumsum(ii).*jj;
out = accumarray( idx(jj)',A(jj)',[],@(x){x'});

Error using accumarray

Second input VAL must be a vector with one element for each row in SUBS, or a scalar.

Error in accelerationrate (line 12)

out = accumarray( idx(jj)',x(jj)',[],@(x){x'});

im getting this error

could u help me with that error?

Show me the whole code..you tried with input.

[johnson saldanha]

T=readtable('finalcycle.xlsx');
data2=[T(:,1),T(:,2),T(:,3),T(:,4)];
data1=table2array(data2);
v=data1(:,2);
ii = zeros(size(v));
jj = v > 0;
ii(strfind([0,jj(:)'],[0 1])) = 1;
idx = cumsum(ii).*jj;
out = accumarray( idx(jj),v(jj),[],@(x){x'});

[johnson saldanha]

or is it possible for me to put it in a matrix. the first column being the first group, second column being the second group and so on
