Illegal use of reserved keyword "end".

i am facing this error i have attached the code below.

[X_norm, mu, sigma] = featureNormalize(X)

X_norm = X;

mu = zeros(1, size(X, 2));

sigma = zeros(1, size(X, 2));

mu = mean (X);

for i=1:size(X, 2)

X(:,i) = X(:,i) - mu(i);

end

sigma = std (X);

for i=1:size(X, 2)

X(:,i) = X(:,i) ./ sigma(i);

end

X_norm = X;

end

Error: File: featureNormalize.m Line: 18 Column: 2

Illegal use of reserved keyword "end".

Error in trynsl (line 14)

X_n = featureNormalize(X);

I think you mean to define a function. The first line needs to be

function [X_norm, mu, sigma] = featureNormalize(X)
