Write Standard Deviation Distance
显示 更早的评论
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

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

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)
v = [10 12 14];
x = ones(1, numel(v))*7;
dist = std(v,x)
disp(['The standard deviation distance is ' num2str(dist)])

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

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