I am having a problem in applying 3d Scattered interpolation in my relative code.

I am having 150 images which are in a stack and i am getting a 3d volume from that slices but the problem is that there i have used the linear interpolation and i want to do it with that 3d scattered interpolation. I am sharing my code here need help.
clc;
close all;
clear
%% Set folders
addpath('./Images1','./Functions')
%% Get names
data = struct2cell(dir("Images1/*.jpg"));
names = data(1,:);
%% Read and save images
imgs = [];
for i = 1:size(names,2)
clc;
fprintf('Reading image # %i \n',i)
% Read image and convert it from RGB to gray
imgs = cat(3,imgs,rgb2gray(imread(names{i})));
end
x_size = (1:1:size(imgs,3));
y_size = (1:1:size(imgs,2));
z_size = (1:1:size(imgs,1));
%z_size = reshape(z_size,y_size, x_size);
vol = meshgrid(x_size,y_size,z_size);
%% Create zig zag shape
% Locatae images in the volume
new_imgs = zeros(size(imgs,1),round(2*size(imgs,2)),size(imgs,3));
% X locations of the images
x_locs = round(((sin((1:size(imgs,3))/10) + 1)/11)*550)+10;
%%
for i = 1:size(imgs,3)
clc;
fprintf('Moving image %i \n',i)
new_imgs(:,x_locs(i):x_locs(i)+size(imgs,2)-1,i) = imgs(:,:,i);
end
disp('Making interpolation ....')
factor = [0.25 0.5 3]; % Factor in x, y and z planes
x_qsize = (1:1/factor(1):size(new_imgs,1));
y_qsize = (1:1/factor(2):size(new_imgs,2));
z_qsize = (1:1/factor(3):size(new_imgs,3));
F = scatteredInterpolant(x_size(:), y_size(:),z_size(:));
[x_query,y_query,z_query] = meshgrid(x_qsize, y_qsize, z_qsize);
% Make interpolation
% Interpolation method
%% method = 'linear'; % You can change this argument
vol_interp = F(new_imgs,y_query,x_query,z_query);
% Load configurations
load('vol_viewer_configs.mat')
figure;
volshow(vol_interp,config1);
figure;
volshow(vol_interp,config2);
.After running the code i am having an error which says that.
Data Points coordinates have inconsistent dimension.
Please have a look and help if someone can.

Hi Huzaifa,
I understand that you are facing a dimension incompatible error while interpolating data points.
Based on the give information and the error, I can confirm that the cause of the error are the inputs to the "mesh grid" function.
Consider making the dimensions equal to resolve the error.
Hope this helps.
Regards,
Nipun
