How do i shift values?

 function sampleReadings = ShiftValues(sampleReadings)
 % sampleReadings: Array containing 3 elements

    % Write three statements to shift the sampleReadings array contents 1 position to the left
    % Note: The rightmost element should be -1
    sampleReadings = 
 end

@Blair: You did not try anything but ask the forum? Why? Do you want us to learn Matlab? Please stop this. If you do not even try to solve your homework by your own, it is a waste of time to ask the forum for help - of your time and the time of the ones who are willing to help you.

If ‘sampleReadings’ is always going to contain only three elements, address the last two elements of the existing ‘sampleReadings’ vector and concatenate -1 to the end.

That’s my best guess. I don’t know what you’re supposed to do, or what you started with.
