How to save images when it requires the following when showing it through figures: imshow(I, [ ])

When processing the image, it is needed to include the square brackets in IMSHOW() command, for example: figure(1); imshow(A,[ ])

When not including the square brackets: figure(2); imshow(A) the image seems incomplete.

I need to save the image that is seen also on the 1st figure. However, i don't know how. using imwrite(A,filename,'jpg'); shows a similar image when using imshow(A)

here is a snippet of my code:

irisImage = imread('C:\test.bmp'); irisImageGrayScale = rgb2gray(irisImage);

                irisImageGrayScale = double(irisImageGrayScale);
    irisImageGrayScale(irisImageGrayScale>170) = nan;
    irisImageGrayScale2 = inpaint_nans(irisImageGrayScale);
    irisImageGrayScale2(irisImageGrayScale2<0)=0;
    irisImageGrayScale2(irisImageGrayScale2>255)=255;

        figure;imshow(irisImageGrayScale2,[])

Make sure irisImageGrayScale2 is uint8 if you want to save it, not double.
