Try these codes below but note that x1 matrix is created randomly, you need to adapt it according to your own matrix. Good luck!
clc; clear;
x1 = randi([0, 100], [51,500,3]);
x2 = reshape(x1,[153,500]);

You must first decide where you want element (i,j,k) of the old matrix be placed in the new matrix.
But usually MATLAB's "reshape" can help.

Try this:
g2 = [g(:,:,1); g(:,:,2); g(:,:,3)];
The result is 153 rows by 500 columns.
Here's a full demo with a 3-D RGB true color image (though it doesn't have the same number of rows and columns, it's just to show you the order where things are put):
g = randi([0, 100], [51,500,3]);
g2 = [g(:,:,1); g(:,:,2); g(:,:,3)];
% Demo (though with different number of rows and columns).
g = imread('peppers.png');
subplot(1, 2, 1);
imshow(g);
axis('on', 'image');
g2 = [g(:,:,1); g(:,:,2); g(:,:,3)];
subplot(1, 2, 2);
imshow(g2);
axis('on', 'image');
