Logical operators in MATLAB are those that link logical statements together and return true (1) or false (0) in a logical matrix depending upon the nature of the logical operator and the value of the components. The following example illustrates this in a very simple way: we see that as soon one of the components of the array evaluates to false, the loop terminates. We will learn how to use both of MATLAB's loop constructs: the for-loop and the while-loop. I've gotten the calculations sorted out but what is the problem now is the color scheme in "image" (or "imagesc"). i just wanna ask,I wan't to make an if statement from vector data, let say vector(1x20) in stateflow, for example if the value vector(1 to 10) > 100 then y=2000 and vector(10 to 20) > 100 then y=4000 ,, so the input is vector from simulink,, can i??? how was the script on stateflow?? or any suggestion???.
