Assign match found with true if the difference between firstsample and secondsample is within thresholdvalue function matchfound = ismatch(first sample, secondsample, thresholdvalue) % firstsample: sample value % secondsample: sample value % thresholdvaiue: maximum difference between samples so that sample are considered equal %assign matchfound with true if the difference between firstsample and secondsample % are within thresholdvalue matchfound = 0; end code to call your function when you click run ismatch((4/5), 0.8, 0.0001)
