Hi all,
How can I determine if a value has changed or not after some operations? For example:
testA = valueA;
% after some operations, testA = valueA or valueB;
% if value of testA changes, continue operation, elseif unchanges, cease operation.

testA = valueA;
oldtestA = testA;
%... do some operations that may change testA
if oldtestA ~= testA %assuming that testA is scalar
%value has changed
else
%value has not changed
end
