V is a row vector containing the variance ], % Create a "random" sample. example V = var (A,w,dim) returns the variance along the dimension dim. Accelerate code by running on a graphics processing unit (GPU) using Parallel Computing Toolbox. If A is a multidimensional array, then h = vartest(x,v,Name,Value) performs For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox). The confidence level, via the critical value; The critical value will essentially be determined from one of two probability distributions: the standard normal distribution, or z score; the t distribution, or t score. The confidence interval of an estimated value is the probability range, based on the estimated value, that contains the true value. Intervals constructed in this way are called confidence intervals. For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox). If h = 0, Compute the variance of A along the second dimension. V = var(A,w,"all") Dimension dim indicates the dimension whose A confidence interval is comprised of two things: Range.
