Unable to perform assignment because the size of the left side is different

I'm at a loss. I've spent hours on this forum looking answers and can't seem to figure out the issue.

Here's the error message I get:

Unable to perform assignment because the size of the left side is 1-by-1 and the size of the right side is 16-by-1.

Error in HW1b (line 130)

answer(i,1) = TeintS;

Here's my code. Sorry it's long. All variables have been previously defined, I've left them out to try ad keep my code shorter

Tair = xlsread(filename,'D3:D26'); %this is outdoor dry bulb air
Tsky = xlsread(filename,1,'I3:I26');
Tgr = Tsky;
QDir_S = xlsread(filename,1,'O3:O26');
QDif_S = xlsread(filename,1,'P3:P26');
QDir_E = xlsread(filename,1,'Q3:Q26');

Start backtracking in the code to figure out why TeintS is not a scalar as you seem to expect it to be. Put in breakpoints and run your code in the debugger. You can also type this at the command line to get your code to pause at the offending line with all variables intact:

dbstop if error
