Question

A health app records a user's weight and displays the change in weight from the previous measurement to the next (i.e. Array(2)-Array(1), Array(3) - Array(2), ...) Assign weightChange win the difference between elements in weightRecord. Ex If weightRecord is [120, 125, 130, 127], then weightChange is [5, 5, -3] function weightChange = CalculateDifference(weightRecord) % weightRecord: Array of weights in pounds % Assign weightChange with the difference between elements in weightRecord weightChange = weightRecord; end

Explanation / Answer

function weightChange = CalculateDifference(weightRecord)
  
for a = 2:length(weightRecord-1)
weightChange(a-1) = weightRecord(a)-weightRecord(a-1);
end
end

weightRecord = [93 87 72 66 95 49 33 21 17];
CalculateDifference(weightRecord)
