I need help with a problem to calculate the square average of any amount of numbers with MATLAB CODE.

Write a program that allows you to enter the user any number of numbers and calculate their quadratic mean. Present PrtScs and desktop tests when the user enters the numbers: 3, -2, 5, 7.

thanks a lot!

Solution

>>maple(\'means:=proc(C::set)
local h;
h:=sqrt(add(j^2,j=C)/nops(C));
\'quadmean=\'.h;
end;))))
>>pretty (sym(maple(\'means({3,-2,5,7})\')))

output:4.66369
