How can i use cell text as variable name input?
I want to use string variables "A" as variable name to output"B".
A={'sample1' 'sample 2' 'sample3'}
like this:
[B]=[sample1, sample2, sample3]
please suggest code made for 2013 matlab version.
Thanks for your help!

The creation of those matrices are not a good idea , if the sizes are consitent use a ND array else use a cell array as is, what your doing is risky and vulnerable. Don't believe see the valuable contributions

A={'sample1' 'sample2' 'sample3'} ;
a = array2table(rand(3)); % an example
a.Properties.VariableNames=A

i managed to write a working code out of this
clc
mabiki=0.8
sample1=[1 2 3 6 7]';
sample2=[nan nan]';
sample3=[4 nan nan 4]';
sample4=[nan nan nan]';
patie2 = padcat(sample1,sample2,sample3,sample4)
[l,w]=size(patie2)
length1=(mabiki*l)-mabiki;
time= (0:mabiki:length1)'
sample1=patie2(:,1)
sample2=patie2(:,2)
sample3=patie2(:,3)
sample4=patie2(:,4)
patie = table(time,sample3,sample4,sample2,sample3);
Fromexcel={'time' 'sample3' 'sample4' 'sample2'};
dataA = patie{1:end,Fromexcel};
matrixfin=array2table(dataA,'VariableNames',Fromexcel)
List=matrixfin.Properties.VariableNames(all(isnan(matrixfin{:,:})))';
if length(List)>=1;
fprintf(' These labels are not found \n');
List=matrixfin.Properties.VariableNames(all(isnan(matrixfin{:,:})))'
end

Rather than this complex and inflexible code:
sample1=patie2(:,1)
sample2=patie2(:,2)
sample3=patie2(:,3)
sample4=patie2(:,4)
patie = table(time,sample3,sample4,sample2,sample3);
just use array2table. In fact it seems like most of your code could be replaced by array2table and a few table operations.
