reshape function error on number of elements

Hi I have the following code

The error appears on the line of "B", however I think that A has 8760 elements and B = 365 x 24 which also is 8760. What could be going wrong?

     A = squeeze(hourly_surplus(1,1,1,:));
        B = reshape(A,365,24);

Where size(A) = 8760 x 1

however I get the error

     Error using reshape
     To RESHAPE the number of elements must not change

Thanks

This works fine for me:

hs = rand(4,4,4,8760);
A = squeeze(hs(1,1,1,:));
B = reshape(A, 365,24);
elms = [numel(hs); numel(A);  numel(B)]

I suggest you set a breakpoint at the line that defines A and look at the workspace variables. Something obviously isn't working the way it should.

What do you mean, "you think"? How about just determining the exact size of A.

 size(A)

then you will know exactly how big A is.

size(A) = 8760 x 1

Something appears to be wrong somewhere because

   A = randn(10,10,10,8760);
   A = squeeze(A(1,1,1,:));
   B = reshape(A,365,24);

should definitely work. Can you copy and paste the above code in your workspace and see that it works?

[Andrew Alkiviades]

yes I have tried you example and it works!

Then something must be happening inside the program, as star strider suggested above set a breakpoint on the line

   B = reshape(A, 365,24);

and then query

size(A)

at the command line, or hover your cursor over the variable A.
