Forward difference approximation: Car temperatures Column arrays measuredTemperature and sample Time contain engine temperature measurement samples, and the time each f(x i+1) fxi)) (x i+1 - xi). Hint: Use the diff function and the element-by-element division operator. Ex. If measuredTemperature = [91.92; 94.97] and sampleTime = [0:1; 2:31, then forwardDiff11: 23] Your Function E save Reset MATLAB Documentation 1 function forwa rdDiff = DerivativeApprox (measuredTemperature, sampleTime) 21% measuredTemperature : Engine temperature measurements in Celsius 31% sampleTime: Time the sample was collected in seconds 4 5 % Assign forwa rdolff with the forwa rd difference approximation given by % (measuredTemperature (n+1) measuredTemperature (n)) / (sampleTime (n+1) forwardDff = measuredTempe rature ; sampleTime (n)) . 9 end
