I am trying to do a function using rgb2ycbcr. It converts the image, then shows it up and saves it, but when I call the function, this error appears:

"Subscript indices must either be real positive integers or logicals."

Here’s my code:

function x = rgb2yuv( x )
x = rgb2ycbcr(x)

imshow(x)
imwrite(x, ‘C:UsersaaaaDocumentsPDIAtividade1imagensx_rgb2yuv.jpg’, ‘jpg’)
end
