I created two arrays and a matrix and I'm trying to use the 'surf' function to plot but its erroring.

this is the code I'm using and it is giving me this error: Error using surf (line 71)

Data dimensions must agree. I'm just not sure what this means or how to fix it.

Error in Lewis_Kailey_ComputerProject1_part3 (line 9)

surf(X,Y,Z)

x=[123456];

y=[1234];

[X,Y]=meshgrid(x,y);

Z = [1 2 3 4 5 6; 2 3 4 5 6 7; 3 4 5 6 7 8; 4 5 6 7 8 9];

disp(Z)

%surf plot

subplot(2,2,1)

surf(X,Y,Z)

title('part3 surf','fontsize',20)

Vectors need some sort of delimiters (spaces, commas, semicolons) to be defined correctly.

x=[123456];                                     % <— This Is The Problem
y=[1234];                                       % <— This Is The Problem

x=[1 2 3 4 5 6];                                % <— This Is The Solution!
y=[1 2 3 4];                                    % <— This Is The Solution!
[X,Y]=meshgrid(x,y)

X = 4×6

1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6 1 2 3 4 5 6

Y = 4×6

1 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3 3 4 4 4 4 4 4

Z = [1 2 3 4 5 6; 2 3 4 5 6 7; 3 4 5 6 7 8; 4 5 6 7 8 9];
disp(Z)

     1     2     3     4     5     6
     2     3     4     5     6     7
     3     4     5     6     7     8
     4     5     6     7     8     9

%surf plot
subplot(2,2,1)
surf(X,Y,Z)
title('part3 surf','fontsize',20)

That appears to work.
