MATLAB: Dimension mismatch??! i cant see how this can be a dimension mismatch

Question

A.textdata(:,3) holds a large set of dates

I am trying to do this:

for i=1:size(A.textdata)

Dates(i,1) = datenum(A.textdata(i,3),'dd-mm-yyyy HH:MM:SS');

Dates2(i,1) = datestr(Dates(i,1),'dd-mm-yyyy ')

end

but i am getting thins error:

> ??? Subscripted assignment dimension mismatch.

Error in ==> Load at 12 Dates2(i,1) = datestr(Dates(i,1),'dd-mm-yyyy ')

Why is that? i cant see how there can be any dimension mismatches??

Answer 1

The problem is that

Dates2(i,1)

is a scalar, but

datestr(Dates(i,1),'dd-mm-yyyy ')

returns a string with length 10.

Dates2(i,:) = datestr(Dates(i,1),'dd-mm-yyyy ');

should work.
