If 'c' is a vector of complex numbers, then 'c' has the data type 'double (complex)'. When 'c' is concatenated with the indices, the result takes the data type ‘double (complex)’. Arrays and vectors can only contain data of one type, so the argument real([1:n]') is converted to a complex number.
To display the values with indices, use the 'fprintf' function, which can display multiple values by passing multiple arguments or an array. Continuing with the example, the following code will display the index along with the value of the vector at that index up to 4 decimal places:
>> fprintf('%d %.4e + %.4ei\n', [(1:length(c)); real(c)'; imag(c)'])
Note that the 'fprintf' function will display results in column order (e.g. the values in rows 1, 2, and 3 in the first column will replace '%d', '%.4e', and '%.4e' respectively). Also note that there is no format specifier for complex numbers, so the real and imaginary parts of the numbers are in separate columns and displayed in scientific notation.
Please run the following command on MATLAB R2018a to know more about 'fprint' function:
web(fullfile(docroot, 'matlab/ref/fprintf.html'))
In particular, the 'formatSpec' argument will allow you to specify formatting options like the precision of the numbers.
When editing vectors, it is recommended to use the variable editor. In the Workspace pane of the MATLAB editor, double click a variable to open the variable editor. This will allow editing of the variable's contents as though it were a spreadsheet.
