理解矢量化

Question

我正在尝试使一些代码更有效,并且想知道如何对此进行矢量化:

%==========================================================================
% MinutesInDayTable.m
% 
% Creates a table identifying every minute as an integer from 0 to 2400.

minuteTableInDay=zeros(24*60,1);
k=1;
for i=1:24
    for j=1:60
        minuteTableInDay(k) = ((i-1)*100+(j-1))*100;
        k=k+1;
    end
end
%~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ end of code ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Answer 1

这是另一个:

minuteTableInDay = (datestr(0:1/24/60:1, 'HHMMSS')-48) * 10.^(5:-1:0)'

玩得开心 :)
