Resize of an image into 640 * 480 pixels

I tried to resize my image using imresize and following code does not work:

function y = fcn(u)

coder.extrinsic('imresize','imwrite');

imresize(u,[640 480]);

imwrite(u,'valli270.bmp');

y = u;

The code is just saving it as bmp file but the resize is not working

You need to save the output of imresize in a variable to use it later. Change your dunction like this.

function y = fcn(u)
  coder.extrinsic('imresize','imwrite');
  y = imresize(u,[640 480]);
  imwrite(y,'valli270.bmp');
end
