Sorry for the silly question, but could anyone show me how to convert a string, such as, '04:55' to numerical values of hour and minute?
Thank you very much.

str2num(strrep('04:55',':',''))

If you want an actual decimal minute value:
x = '04:55'
y = str2double(regexp(x,':','split'))
z = y*[1;1/60]
(Leave off the last line if you just want minutes and seconds as separate array elements.)

It's very nice to see the use of regexp to split the string into two values.
This could be a even better solution.
Thank you very much.

Is the string fixed width, with a leading 0? If so then,
H = T(1) - '0' * 10 + T(2) - '0';
M = T(4) - '0' * 10 + T(5) - '0';
Or
H = str2num(T(1:2));
M = str2num(T(4:5));
Or
H = [10 1] * (T(1:2)-'0').';
M = [10 1] * (T(4:5)-'0').';
