If you use the syntax
save FILENAME VARIABLENAME
or
save('FILENAME', 'VARIABLENAME')
then if no variable named VARIABLENAME exists in scope, you would get that error message.
For example that could happen if you think you are always computing something and so try to save it, but it turns out that there are cases where the value is not actually computed.
if V
result = 1
elseif ~V
result = 2;
end
save Output.mat result
This will not assign anything to result in some cases where V is a vector or array or is empty.
