I am trying to create a .txt file with the following data in this format.

e 5.4 300+2i

f 3.3 3+200i

c 2.2 9.9+210i

f 1.1 2.290+0.1i

with e,f,c,f beign strings, and the last numbers being complex numbers.

I'm not sure what the best way to go about this. Should I create a cell array and then use fprintf to create a .txt file?

If you have R2013b or later, create the cell array, then use the cell2table function to create a table, then use writetable to write the file.

Example —

C = {'e' 5.4+300+2i
     'f' 3.3+3+200i
     'c' 2.2+9.9+210i
     'f' 1.1+2.290+0.1i};
T = cell2table(C)
T =
    4×2 table
      C1         C2    
      ___    __________
      'e'    305.4+2i  
      'f'      6.3+200i
      'c'     12.1+210i
      'f'     3.39+0.1i

Then write to the file.

reconstructed = [C(1), num2cell(C{2}), num2cell(C{3})];

I did not realise this is a homework assignment. My objective was to use writetable so you can use readtable to read it again. The writetable function defaults to a comma-delimited text file, so in your textscan call, specify the delimiter to be a comma. That should work.
