Write Standard Deviation Distance

I am asked to write a function called standard_deviation_distance that takes as input a data vector [1xN] v and a number x [1x1], in that order. And I have code to call your function:

v = [10 12 14];
x = 7;
dist = standard_deviation_distance(v,x)% =-2.5

Answer 1

[VBBV]

v = [10 12 14];
x = ones(1,numel(v))*7;% length of x vector (weights) for each element and to be same as vector v
dist = standard_deviation_distance(v,x);
disp(['The standard deviation distance is ', num2str(dist)])

The standard deviation distance is 1.633

function y =  standard_deviation_distance(v,x)
y = std(v,x);
end

Answer 2

[Himanshu Desai]

function y = standard_deviation_distance(v,x)  
    m = mean(v);
    s = std(v);
    y = (x-m)/s;
end

dist = -2.500

v = [10 12 14];
x = 7;
y = standard_deviation_distance(v,x)

Answer 3

[Mark]

v = [10 12 14];
x = ones(1, numel(v))*7;
dist = std(v,x)

dist = 1.6330

disp(['The standard deviation distance is  ' num2str(dist)])

The standard deviation distance is  1.633

I corrected the nume1() call to be numel()

[Torsten]

I don't see a difference to @VBBV 's solution (except for "nume1" instead of "numel").

Maybe it was meant as "test test test".

[Walter Roberson]

@VBBV solution involved a function (as was required by the terms of the question)
