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.

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.
