hello sir,i am new in matlab.By using imhist show an error

RGB = imread('figure.jpg'); redvalue=RGB(:,:,1); greenvalue=RGB(:,:,2); bluevalue=RGB(:,:,3); sprintf('Value of the red,green and blue pixel is %d,%d,%d',redvalue,greenvalue,bluevalue) imshow(RGB) title('RGB IMAGE') I = rgb2gray(RGB);%figure,imshow(I) title('gray image') figure,imhist(I) title('histogram') T=80; it=im2bw(I,T/255); figure,imshow(it);

%I have tested it with a different image, No error

RGB=imread('1.jpg');
redvalue=RGB(:,:,1); 
greenvalue=RGB(:,:,2); 
bluevalue=RGB(:,:,3); 
sprintf('Value of the red,green and blue pixel is %d,%d,%d',redvalue,greenvalue,bluevalue);
figure, imshow(RGB),title('RGB IMAGE') 
I=rgb2gray(RGB);
figure,imshow(I),title('gray image') 
figure,imhist(I),title('histogram') 
T=80; 
it=im2bw(I,T/255); 
figure,imshow(it);

Here I have ignored the warning

Attach M file.

I have changed the image name to athira.jpg %it is not an issue

    RGB=imread('athira.jpg');
    redvalue=RGB(:,:,1);
    greenvalue=RGB(:,:,2);
    bluevalue=RGB(:,:,3);
    sprintf('Value of the red,green and blue pixel is %d,%d,%d',redvalue,greenvalue,bluevalue);
    figure,imshow(RGB),title('RGB IMAGE');
    I=rgb2gray(RGB);
    figure,imshow(I),title('gray image')
    figure,imhist(I),title('histogram')
    T=80;
    it=im2bw(I,T/255);
    figure,imshow(it),title('binary image');
    % binImage = ~BW;
    %  binImage = 1-BW;
    % % binImage = (BW == 0);
    % imwrite(binImage,'ss1.png');
    % background = imopen(BW,strel('square',80));
    % J=imsubtract(BW,background);
    % imshow(J)
    %title('background subtraction'

No, this is not an issue

these are the error shown in command window
