loop over a cell and combine cell columns into one column

i have a cell array e.g

[1,10,18,24,31,40,0]	[]	2.0673943	2.0874443	2.1595383	2.2108727	2.2004662	2.1298561	[]
[2,11,19,25,32,41,49,-1]	[]	2.5844460	1.4922142	1.9188881	2.1945801	2.1078224	2	2.0430222
[3,12,20,26,33,43,-1]	[]	2.4619789	2.1192665	2.1591911	2.2104111	2.2032127	2.1415558	[]
[4,13,21,27,34,-1]	[]	2.7252617	1.4234924	1.8084259	1.9428711	2.0691185	[]	[]

i want to take every column and combine them together into a row vector into the 2nd column of my cell.

i did this but i cant find my mistake. my code takes every column and combines it into the 2nd column but in the next cell he takes the previous ones too.

for i = 1:length(element_row)
for k = 1:length(element_row{i,1})
Abstand = element_row{i,k+1};
row = [row,Abstand];
element_row{i,2} = row;
end

my output is:

[1,10,18,24,31,40,0]	[2.0673943,2.0874443,2.1595383,2.2108727,2.2004662,2.1298561]	2.0673943	2.0874443	2.1595383	2.2108727	2.2004662	2.1298561	[]
[2,11,19,25,32,41,49,-1]	1x13 single	2.5844460	1.4922142	1.9188881	2.1945801	2.1078224	2	2.0430222
[3,12,20,26,33,43,-1]	1x19 single	2.4619789	2.1192665	2.1591911	2.2104111	2.2032127	2.1415558	[]
[4,13,21,27,34,-1]	1x24 single	2.7252617	1.4234924	1.8084259	1.9428711	2.0691185	[]	[]

but i want

[1,10,18,24,31,40,0]	[2.0673943,2.0874443,2.1595383,2.2108727,2.2004662,2.1298561]	2.0673943	2.0874443	2.1595383	2.2108727	2.2004662	2.1298561	[]

Where C is your cell array:

>> C(:,2) = cellfun(@cell2mat,num2cell(C(:,3:end),2),'uni',0)
C = 
    [1x7 double]    [1x6 double]    [2.0674]    [2.0874]    [2.1595]    [2.2109]    [2.2005]    [2.1299]         []
    [1x8 double]    [1x7 double]    [2.5844]    [1.4922]    [1.9189]    [2.1946]    [2.1078]    [     2]    [2.043]
    [1x7 double]    [1x6 double]    [ 2.462]    [2.1193]    [2.1592]    [2.2104]    [2.2032]    [2.1416]         []
    [1x6 double]    [1x5 double]    [2.7253]    [1.4235]    [1.8084]    [1.9429]    [2.0691]          []         []

Checking the contents of each cell in the second column:

>> C{:,2}
ans =
       2.0674       2.0874       2.1595       2.2109       2.2005       2.1299
ans =
       2.5844       1.4922       1.9189       2.1946       2.1078            2        2.043
ans =
        2.462       2.1193       2.1592       2.2104       2.2032       2.1416
ans =
       2.7253       1.4235       1.8084       1.9429       2.0691

Error using cell2mat (line 45)

All contents of the input cell array must be of the same data type.

should i change the data type ? if so how can i change them to e.g. single or double.

EDIT: okay i got it.

i just converted my input data few steps ahead into "double-precision" now it works

thank you very much
