i have a code and i am unable to save the final image using imwrite, so how to save the image? code is given below

m=256;
n=256;
f1=10;  % No. of vertical fringes
f2=0;  % No. of horizontal fringes
for i=1:m
    for j=1:n
        a1(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)-2*pi/3));
        a2(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)));
        a3(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)+2*pi/3));
      end
  end
  Color=zeros(256,256,3);
  Color(:,:,1)=a1;
  Color(:,:,2)=a2;
  Color(:,:,3)=a3;
  imshow(Color,[]);

在 MATLAB Online 中打开

m=256;
n=256;
f1=10;  % No. of vertical fringes
f2=0;  % No. of horizontal fringes
a1 = zeros(m,n) ;
a2 = zeros(m,n) ;
a3 = zeros(m,n) ;
for i=1:m
    for j=1:n
        a1(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)-2*pi/3));
        a2(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)));
        a3(i,j)=exp(1i*(2*pi*(f1*j/n+f2*i/m)+2*pi/3));
      end
  end
  Color=zeros(m,n,3);
  Color(:,:,1)=a1;
  Color(:,:,2)=a2;
  Color(:,:,3)=a3;
  imshow(Color,[]);
    imwrite(Color,'myimage.jpg')
