Remove pixel == 1 from an RGB image

Hi everybody, hi have an RGB image and i want to remove all pixels which were equal to 1 from the following command:

FIND=(A(:,:,1)>=175 & (A(:,:,1)<=193));

with A that is the 4000x6000x3 uint8 image.

YOu cannot remove them, replace them with any other value.......

A = I(:,:,1) ;
idx = A>=175 & A<=193;
A(idx) = 0 ;
I(:,:,1) = A ;

Thank you for the answer, but what is I?

I is your RGB image of size (m,n,3)

[Riccardo Rossi]

okay, but i just want to select (A(:,:,1)>=175 & (A(:,:,1)<=193)) and not (A(:,:,i)>=175 & (A(:,:,i)<=193))

Okay..then remove the loop.....Edited the code.
