I am trying to save a matlab project file for future use after loading some data. I need to save six variables, but the project is only saved with three of the six I specified. I also tried saving the whole project, and it ended up deleting the two most important variables of the project! Here is the relevant code:

atmyr = 1993;
diam = 50;
.
.
.
around = floor(A(:,1:2)./diam).*diam;
lround = floor(AL(:,1:2)./diam).*diam;
unq = intersect(around, lround, 'rows');
sfile = sprintf('LoadQ_%im_%i_q2.mat',diam,atmyr);
save(sfile,'AL','A','lround','around','unq','diam');
save('matlabtest.mat');

The code runs fine and no errors are generated. The first save function only saved the unq, diam, and around variables. The second save function appears to save all variables except, again, 'A', 'AL', and 'lround'. 'A' and 'AL' are very large non-sparse matrices (hundreds of millions of rows by 7 columns). 'around' and 'lround' have the same number of rows as 'A' and 'AL' with just 2 columns. 'unq' is ~140,000 by 2. 'Diam' is a number. I will try switching the last two save commands and see if that does anything helpful. Otherwise, I have no idea what the problem could be. Does anyone have any ideas?
