P must be a scalar or non-empty vector of real values between 0 and 100 When Dim is not 1 (non-tall dimension), exact computation is more efficient. Try setting the 'Method' parameter to 'exact' instead. Percentile or quantile of a tall array in the first dimension is only supported for tall column vectors. The value of {0} must not be complex. The value of {0} must not be sparse. The value of {0} must not be an object. The value of {0} must not be a gpuArray. The value of {0} must be a floating point array. The value of {0} must be a numeric array.
