I have a 422x1 cell which contains strings as below
0
0
[35.1600000000000,35.1600000000000]
0

35.1600000000000

[35.8200000000000,35.8200000000000]
0

35.8200000000000
0
[36.6600000000000,36.6600000000000]
How can i split this cell so that i get 2 different cells. 1 of them is just the first value, the second of them are zeros except when there are 2 values in the string.

A = {0,0,[35.1600000000000,35.1600000000000],0,0,35.1600000000000, ...
0,0,[35.8200000000000,35.8200000000000],0,0,35.8200000000000,0,[36.6600000000000,36.6600000000000]};
B = zeros(size(A,2), 2);
for i = 1:length(A)
B(i,1) = A{i}(1);
if size(A{i}, 2) > 1
B(i,2) = A{i}(2);
end
end
B = 14×2

Use cellfun, two possibilities:
function [val1,val2] = myfun1(x)
val1 = x(1);
if isscalar(x)
val2 = 0;
else
val2 = x(2);
end
end
>> C0 = {1; 2:3; 4:5; 6}
>> [C1,C2] = cellfun(@myfun1,C0,"UniformOutput",false)
>> C12 = [C1 C2]
C12 =
4×2 cell array
{[1]} {[0]}
{[2]} {[3]}
{[4]} {[5]}
{[6]} {[0]}
or
function cellRowOut = myfun2(x)
if isscalar(x)
cellRowOut = {x 0};
else
cellRowOut = {x(1) x(2)};
end
end
>> C12 = cellfun(@myfun2,C0,"UniformOutput",false)
C12 =
4×1 cell array
{1×2 cell}
{1×2 cell}
{1×2 cell}
{1×2 cell}
>> C12 = vertcat(C12{:})
C12 =
4×2 cell array
{[1]} {[0]}
{[2]} {[3]}
{[4]} {[5]}
{[6]} {[0]}
