csvread
fills empty delimited fields with
zero. When the csvread
function reads data files
with lines that end with a nonspace delimiter, such as a semicolon,
it returns a matrix, M
, that has an additional
last column of zeros.
csvread
imports any complex number as a whole
into a complex numeric field, converting the real and imaginary parts
to the specified numeric type. The table shows valid forms for a complex
number.
Form  Example 
±<real>±<imag>ij
 5.73.1i

±<imag>ij
 7j

Embedded white space in a complex number is invalid and is regarded
as a field delimiter.
