Second input 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 be real. The 'approximate' method does not support object inputs such as gpuArray. The first input must be numeric. First input must be a numeric array for the 'approximate' method.
