MATLAB procedure is presented for calculating the exact factors used to find of two-sided tolerance limits in a normal distribution with unknown parameter values. The proposed procedure allows using arbitrary combinations of the sample size and the degrees of freedom of estimated variance. The procedure can be used in systems for processing the results of statistical quality control created on the basis of MATLAB.
