Returns a two-tailed probability from the Student t distribution. TDIST(t,df) returns the two-tailed probability P associated with the test statistic t and df degrees of freedom.

The argument t can be a real number or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the TDIST function applied to all elements.
