Hi, I have a function that edits some dates in a column to serial dates. How can I overwrite the matrix I pass into the function? When I run for example:
(dateMatrix) ----> new dateMatrix
But what happens is I get the ans matrix returned.
function A = changeDates(A)
d = A(:,1);
d=num2str(d)-0;
Y=str2num(char(d(:,1:4)));
M=str2num(char(d(:,5:6)));
D=str2num(char(d(:,7:8)));
sd=datenum(Y,M,D)
A(:,1) = sd;
clear d Y M D sd
thanks friz

Also just so you know, there is no need to clear the function variables before the function exits. All simple variables defined in a function are destroyed automatically on exit.
