    Here is an example:

    file.csv

    name,age,gender
aaa,20,m
bbb,25,
ccc,,m
ddd,40,f

    readMyCSV.m

    fid = fopen('file.csv','rt');
C = textscan(fid, '%s%f%s', 'Delimiter',',', 'HeaderLines',1, 'EmptyValue',NaN);
fclose(fid);
[name,age,gender] = deal(C{:});

    The data read:

    >> [name num2cell(age) gender]
ans = 
    'aaa'    [ 20]    'm'
    'bbb'    [ 25]    '' 
    'ccc'    [NaN]    'm'
    'ddd'    [ 40]    'f'
