MATLAB: Reading complex numbers from Excel

Question

Hi,

I have an excel sheet which has one column consisting of series of rows filled with complex numbers

eg:

-0.00340875447356980 – 0.143829744894360i

0.00826437724550120 – 0.0203601960662560i

0.0175899073253476 + 0.0143665796766208i

I have two variables 'a' and 'b'. I would like to import all the real values from the excel sheet to 'a' and all the imaginary values to 'b'.

Answer 1

Step.1: Reading values from the excel sheet (see attachment).

[num,txt,raw] = xlsread('imag_real.xlsx')

Step.2: Apply a str2double to each cell of a cell array i.e. raw

data = cellfun(@str2double,raw)

Step.3: Storing real values to a and imaginary values to b

a = real(data);b = imag(data);
