Program Design of Linear Measurement Uncertainty Evaluation Based on Matlab

Because of the complexity of the form and position error of measurement and measurement results of diversity, lead to actual measurement result of form and position error measurement of the uncertainty evaluation has become a problem.In particular, the measuring points are more, the measurement data is difficult to deal with, and the accuracy of processing the result is difficult to guarantee.In this paper, the evaluation process of the uncertainty based on the straightness measurement is designed.At the prompt of the program command, the linear degree error can be obtained by the input measurement value, and the uncertainty of the linear degree can be obtained by the input single point measurement uncertainty.The program is designed based on the method of using the GUM method and the Monte Carlo method, which is used to measure uncertainty, and can be obtained by two different evaluation results.The degree of unmeasured and the complexity of measuring data is affected. Through data verification, the program is reliable and accurate.It provides convenient and efficient data processing method for measuring uncertainty of linear degree.By measuring data verification, the program is accurate and reliable, and has certain practical application value and extension significance.
