How to create an structure fields from an cell array?

I have the following code:

data1 = xlsread('data1.xlsx');
namesoftags = {'timeaxis','cputime','flux','volts'};
for i =1:4
    S = cell2struct(data1(:,i),namesoftags(i));
end

data1 has the following data:

It's a 5x4.

1	5	    298	        53
2	9	    284	        35
3	0	    58            2329
4	17	    892	        67
45	183	    45	        29

But its gives me this error:

Error using cell2struct
Unknown command option.

Error in structuredemo (line 4)
    S = cell2struct(data1(:,i),namesoftags(i));    

Thankyou

Use readtable() requires 2016b or later to read the excel file and then give table the variable names and then simply use table2struct() to convert it into structure with fieldnames(which will be the variable names) , I suspect loop is superfluos in your case.

Thank you that works, but now if I try to plot one of the fields. It doesnt work.

The old way

%%
namesoftags = {'timeaxis','cputime','flux','volts'};
data1 = [ 1,5,298,53
          2,9,284,35
          3,0,58,2329
          4,17,892,67
          45,183,45,29 ];
%%
S = cell2struct( num2cell(data1,1), namesoftags, 2 );

Display result

>> S
S = 
  struct with fields:

    timeaxis: [5×1 double]
     cputime: [5×1 double]
        flux: [5×1 double]
       volts: [5×1 double]
