matlab代码解决，怎么运行

Question

function T = f2(Image)
Gray=rgb2gray(Image);

[M,N] = size(Gray);

for i = 1:M

for j = 1:N

    for n = 1:256/16

        if (n-1)*16<=Gray(i,j)&&Gray(i,j)<=(n-1)*16+15

            Gray(i,j) = n-1;

        end

    end

end

end

P = zeros(M,N,4);

for m = 1:16

for n = 1:16

    for i = 1:M

        for j = 1:N

            if j<N&&Gray(i,j)==m-1&&Gray(i,j+1)==n-1

                P(m,n,1) = P(m,n,1)+1;

                P(n,m,1) = P(m,n,1);

            end

            if i>1&&j<N&&Gray(i,j)==m-1&&Gray(i-1,j+1)==n-1

                P(m,n,2) = P(m,n,2)+1;

                P(n,m,2) = P(m,n,2);

            end

            if i<M&&Gray(i,j)==m-1&&Gray(i+1,j)==n-1

                P(m,n,3) = P(m,n,3)+1;

                P(n,m,3) = P(m,n,3);

            end

            if i<M&&j<N&&Gray(i,j)==m-1&&Gray(i+1,j+1)==n-1

                P(m,n,4) = P(m,n,4)+1;

                P(n,m,4) = P(m,n,4);

            end

        end

    end

        if m==n

            P(m,n,:) = P(m,n,:)*2;

        end

end

end

for n = 1:4

P(:,:,n) = P(:,:,n)/sum(sum(P(:,:,n)));

end

H = zeros(1,4);

for n =1:4

for i = 1:16

    for j = 1:16

         if P(i,j,n)~=0

            H(n) = -P(i,j,n)*log(P(i,j,n))+H(n);

    T(1)=mean(H);       T(2) = std(H);

Answer 1

你应该定义一个IMAGE变量
比如说

Image = imread('文件名.jpg');

然后再进行操作
