Hi,
I have a matrix with 18 columns and over 100'000 rows and in each rows there are stored different characteristic for a specific data. In column 6 is the date in this form:
for example 730853 for the 02-Jan-2001
Now I would like to create a new matrix that consists only if those rows where the date refers to a Wednesday, is that possible?

Example
d1=730853
dates=datestr(d1:d1+100,'ddd-mm-yyyy')
M=[cellstr(dates) num2cell((1:101)')]
M=M(ismember(dates(:,1:3),'Wed','rows'),:)
