By removing if you mean crop then,
Image(row_start:row_end,col_start:col_end)=[];

Let's make it crystal clear: You flat out cannot do what Rushikesh said in general. Just try it and see. The only way to get it to work is like David said and if those indexes indicate an entire row or column, meaning the start has to be 1 and the ends have to be "end".
What you can do is what I said, and that is to create new, smaller images where you've identified the rectangles in the image and used imcrop() to crop those out, thus forming the new images but leaving the original image intact.

You can't have "holes" in the image - it must remain rectangular. Like David says, you can replace with zeros or some value but you can't have just null/nothing. imcrop() will produce a separate smaller image with the original left intact, unless the output of imcrop is also the original image.

You asked this before somewhere and I told you to use a modified median filter.
Please post this as a new question (not here) and if you can't figure it out, I'll give you a complete demo.
