WebIn this case, tcdf expands each scalar input into a constant array of the same size as the array inputs. Each element in p is the cdf value of the distribution specified by the corresponding element in nu, evaluated at the corresponding element in x. Example: [ … h = ttest2(x,y) returns a test decision for the null hypothesis that the data in vectors x … where ν is the degrees of freedom and Γ( · ) is the Gamma function. The result y is … If either or both of the input arguments p and nu are arrays, then the array sizes …
