Forward difference approximation: Car temperatures Column arrays measured Temperature and sample Time contain engine temperature measurement samples, and the time each sample was collected, respectively. Assign with the forward difference. The forward difference approximation (x_) is (x_ + 1) - (x_)/(x_i + 1 - x_i). Ex. If measuredTemperature = [91; 92; 94; 97] and sample Time = [0; 1; 2; 3] then forwardDiff = [1; 2; 3] function forwardDiff = DerivativeApprox(measuredTemperature, sampleTime) % measuredTemperature: Engine temperature measurements in Celsius % sampleTime: Time the sample was collected in seconds % Assign forwardDiff with the forward difference approximation given by % (measuredTemperature(n + 1) measuredTemperature(n))/(sampleTime(n + 1) - sampleTime(n)) forwardDiff = measuredTemperature; end DerivativeApprox ([91; 92; 94; 97], [0; 1; 2; 3])
