Help Assigning values of large matrix into kth customer over 24 hours of time table

Hi i have a 1511x65 double matrix. as picture shows... column 1 is data for 1 customer power usage over 24 hours in 63 days. so 63 x 24 = 1511. which is why its 1511x65..where 65 is the amount of customers.

so i want to make a for loop so i can call one and/or all customers power usage over 24 hours. since it is 63 days envolved..i take the mean of the time for example 3 o'clock of all the 63 days. and i will end up with 1 value instead of 63 different values in the end..(this i know how to) i have made a manual code for 1 customer..but is there a way to make it a loop for all of them without the manual way. here is the manual code:

customer1 = x(:,1);
trow = 24;
tcol = ceil(length(customer1)/trow);
k1 = [customer1; nan(tcol*trow-length(customer1),1)];
k1 = reshape(k1,trow,tcol);
  time = [0:23]';
  plot(time,mean(k1,2))

regards a curious matlab user :D

So the result could be after the for loop:

when i call, lets say customer 5 i should be able to do this:

customer5 = k1(:,5) and i have a matrix of: 24x1 of customer 5.
