function g = sigmoid(z)
|
|
%SIGMOID Compute sigmoid function
|
|
% g = SIGMOID(z) computes the sigmoid of z.
|
|
|
|
% You need to return the following variables correctly
|
|
g = zeros(size(z));
|
|
|
|
% ====================== YOUR CODE HERE ======================
|
|
% Instructions: Compute the sigmoid of each value of z (z can be a matrix,
|
|
% vector or scalar).
|
|
g = 1 + exp(-1*z);
|
|
g = g.^(-1);
