You may note the slight difference between "stdev" and "Stdev", which is of course all the greater the smaller the data sample is.

    Additional to what Cornel wrote, you can also get all three results in one go by using the Nabla operator (gradient)

    Using the symbolic engine, you can even define the function without explicitly specifying the function arguments and thus use a notation similar to the one you used in the question. However, I don't really recommend doing so.

      Thank you for you help. Are there any functions in Prime that would help me to get the standard deviation and mean value of a matrix generated by random numbers?

      How about the built in functions 

      stdev()

      mean()

      ?

      Check the help info to find out how to use them.

       

      Success!
