My code is as follows
Mr_theo = (W_R + Up)./a2;
where W_R is a 1x1 double, Up is a 100x1 symbolic array, and a2 is a 100x1 symbolic array. All numbers are positve, however, they consistently are yeilding a negative number, which makes no sense to me at all. Is this a syntax error? the addition of W_R and Up is causing matmatical errors.

They are not negative numbers but probably represented in scientific notations.
format longg % at the beginning
Because the answers I get is all positive.

So when I run the same formula in a new script all my numbers work, but when I run the script all together (even in a new m file), it outputs the incorrect negative stuff. This really confuses me - the format longg did not change it. Any more ideas?
