I would like to adjust the Jet colormap such that the 0 value (or center) is white, while, all the other colors remain the same. Is there a simple way to do this?

Thank you in advance.

Dude, do it like this:

% Read in standard MATLAB grayscale demo image.
grayImage = imread('tire.tif');
imshow(grayImage, []);
title('Original Grayscale Image');
set(gcf, 'Position', get(0,'Screensize')); % Enlarge figure to full
screen.

myColorMap = jet; % Make a copy of jet.
% Assign white (all 1's) to black (the first row in myColorMap).
myColorMap(1, :) = [1 1 1];
colormap(myColorMap); % Apply the colormap
